+TO DO
+
+- Address the remaining "---" issues
+
+- Get the rest of the unit tests working
+ - Ensure we can parse/print descriptor.proto, unittests.proto, etc
+ - unittests.proto completely fails when 'optimize = SPEED'
+ - Ensure we can (de)serialize "golden" data against unittests.proto
+ - Get the rest of Bob Brown's tests working
+[ - Convert examples into a test suite ]
+[ - Implement 'protobufs-equal' predicate ]
+
+- Get "namespaces" (i.e., nested classes) fully working
+[ - Messages and enums should have a 'fully-qualified-names' slot ]
+[ that records both symbols and strings, and in the correct package ]
+[ - Printers need to print qualified names, as needed ]
+[ - 'find-message' and 'find-enum' need to search namespaces ]
+[ if the quick compare against the name/class fails ]
+ - 'message Foo { message Bar { ... } ... }'
+ should (maybe!) produce a Lisp class defaultly named 'foo.bar'
+ - Add a keyword arg, :class-name, that overrides this convention;
+ in .proto files this should be called lisp_class
+ - Also, add :slot-name for slots and :type-name for enums
+ (called lisp_slot and lisp_type in .proto files)
+ - Or maybe not, since 'foo.bar' isn't very Lispy;
+ for the most part, packages provide enough room to avoid name clashes
+
+- Get 'merge-from-message' fully working
+ - See the place in 'deserialize-object' that needs to merge, too
+ - Maybe this isn't so useful in Lisp, where I'd prefer to encourage
+ a more function style
+
+- Lose 'proto-class', replace it with 'proto-type';
+ its type is (or null symbol)
+ 'proto-type' should always be the name from the Lisp side
+[ All 'define-xxx' macros should have, as their first argument, ]
+[ a type (not a "name") ]
+[ In .proto files, there should be an 'option lisp_name="pkg:name"' ]
+[ which can be used to override the 'proto->class-name' default ]
+[ for messages and enums ]
+
+- Refactor 'protobuf-field' so the names are clearer:
+ - 'proto-value' should be the Lisp name of the slot
+ (this is already the case)
+ - Add new 'proto-field' slot,
+ which will hold the Protobufs name of the field
+ (this used to be in 'proto-name')
+ - Lose the existing 'proto-type' slot,
+ then rename the 'proto-class' slot to 'proto-type';
+ this will hold the Lisp name of the slot type
+ - 'proto-name' will hold the Protobufs name of the field type
+ (this used to hold the Protobufs name of the field)
+[ - &key name should give the Protobufs name for the field ]
+[ - 'option lisp_name="pkg:name"' should give the Lisp name for the slot ]
+
+[- Need search paths in the ASDF .proto module ]
+
+[- Make 'import' really work ]
+[ - *all-protobufs* should record keyed by pathname, too ]
+[ - 'import' should not bother loading if the import is present, ]
+[ and should record the imported schema when it's done ]
+[ - 'find-message' and 'find-enum' should search imports, too ]
+
+[- Implement 'vector-of' in addition to 'list-of' ]
+
+[- Do we need 'has-extension' and 'clear-extension'? ]
+[ If so, just generate methods for them in 'define-extend' ]
+
+[- 'package'/'lisp_package' should create the package, if necessary. ]
+
+[- Don't generate 'import "net/proto2/proto/descriptor.proto"' and ]
+[ 'extend proto2.MessageOptions { ..}' lines unless we need to include ]
+[ one of the lisp_* options in the generated model ]
+
+[- Handle 'import' ]
+[ It should probably just compile/load the file when the import ]
+[ is seen ]
+[ - The Lisp macros should be able to import both .lisp and .proto files ]
+[ - The .proto parser should only be able to import .proto files ]
+
+[- Handle 'extension' and 'extends' ]
+[ - 'define-extension' just declares the extension within a message ]
+[ and adds it to 'proto-extensions' for the message ]
+[ - Easiest is to add an "extension-p" flag to 'protobuf-message' ]
+[ - Define new 'define-extends' macro ]
+[ which *copies* all slots from the message being extended, ]
+[ then just adds the extension fields as (flagged) ordinary fields ]
+[ with reader/writer function (see below) ]
+[ - Factor out field-processing code from 'define-message' ]
+[ - If we do it this way, no other special magic is needed ]
+[ Serialization, e.g., should just work ]
+[ Scoping should also just work ]
+[ - We will need 'proto-writer' as an analog to 'proto-reader' ]
+[ - Get deserialization working; ]
+[ Need to call the 'proto-writer' function if its around ]
+[ instead of just using (setf (slot-value ...) ...) ]
+[ - Don't forget to check that the "extends" indexes match ]
+[ what was declared by 'define-extension' ]
+[ - And don't allow overlapping extension indexes ]
+[ - Generate new getter and setter methods for each extended slot: ]
+[ (let ((an-int 10)) ]
+[ (declare (type (or integer null) an-int)) ]
+[ (defmethod an-int ((object extendable-foo)) ]
+[ an-int) ]
+[ (defmethod (setf an-int) (val (object extendable-foo)) ]
+[ (declare (type (or integer null) val) ]
+[ (setq an-int val)))) ]
+[ - Handle "extends" in the parser, too ]
+
+[- Support "deprecated" groups. Sigh. ]
+[ - Need 'proto:define-group', which is like 'define-message' ]
+[ - Need to parse 'group' things ]
+[ - "option group Locator = 1 { ... }" ]
+[ means create a submessage (and class!) called "Locator" ]
+[ whose field is named "locator" (note lower case) ]
+[ then just treat it like a message ]
+[ - Need a printer for groups, too ]
+[ - Make 'proto-extension-p' be 'proto-message-type', ]
+[ which is one of :message, :extends or :group ]
+[ - (De)serialization of groups uses a start and end tag, ]
+[ and the end tag counts as part of the group length ]
+[ - Serialization uses the start-group wire type, ]
+[ then serializes the message, ]
+[ then writes the end-group tag ]
+[ - Deserialization works the usual way, ]
+[ except that it stops at a matching end-group tag ]
+[ (i.e., has the same field number as the start tag) ]
+[ - Add new 'end-tag' argument to 'serialize-object' and ]
+[ the 'serialize' internal function, it's the expected ]
+[ end tag value to indicate end-of-group; if the default ]
+[ value for this is 0, then the (i= tag 0) test can be ]
+[ changed to (i= tag end-tag) (sweet!) ]
+
+[- We need both 'package' and 'lisp-package' for protobufs ]
+[ 'package' gets set from the 'package' line in .proto files ]
+[ 'lisp-package' gets set from a new 'option lisp_package="pkg"' ]
+[ 'define-protobuf' needs both :package and :proto/:lisp-package ]
+
+[- Speed up 'list-of' by shadowing the Quux version, ]
+[ and don't do any type-checking (!) ]
+[ Having done this, we can probably remove the hack of using map:map, ]
+[ which should make deserialization much faster ]
+
+[- 'proto-name' should always be the name from the Protobufs side; ]
+[ its type is (or null string) ]
+[ All 'define-xxx' macros should have '&key name' which gives the Protobufs ]
+[ name, which can be used to override the 'class-name->proto' default ]
+
+[- 'class-override' should be called 'alias-for'; ]
+[ its type is (or null symbol) ]
+[ 'define-message' and 'define-enum' both get '&key alias-for' ]
+
+[- 'find-message' and 'find-enum' should only look at (the new) 'proto-type', ]
+[ and never (the new) 'proto-alias-for' ]
+
+[- 'deserialize-object' uses the alias when it calls 'make-instance', ]
+[ or if there is no alias, 'proto-type' ]
+
+[- 'serialize-object' and 'object-size' should take both 'object' and 'type' ]
+[ args, and should not call 'class-of' (and do call it "type") ]
+[ The 'cl' (and 'class') locals in '(de)serialize-object' and 'object-size' ]
+[ should instead be called 'type' ]
+[ In .proto files, there should be 'option lisp_alias="pkg:name"' ]
+[ that gets used to fill in 'proto-alias-for' ]
+
+[- 'serialize-object' and 'object-size' never use the alias; ]
+[ instead all the "dispatching" should be done of off 'proto-type', ]
+[ Ditto, 'print-text-format' ]
+
+[- Deserialization should stop if it sees a #x00 in the position where ]
+[ it's expecting a tag, since no tag can be #x00 (fields start at 1) ]
+
+[- The "name" of a protobuf should be the camel-cased file name ]
+[ The "type" of a protobuf should just be the file name as a keyword symbol ]
+
+[- RPCs should have 'input-name', 'input-type', 'output-name' and 'output-type' ]
+[ The "name" ones are for the Protobufs side ]
+[ The "types" ones are for the Lisp side; we look up on "type" only ]
+[ In the Lisp, the RPC types can be either 'type' or '(type :name <name>)' ]
+[ In .proto files, there should be an 'option lisp_name="pkg:name"' ]
+[ which can be used to override the 'proto->class-name' default ]
+[ for the name of the RPC function ]
+
+[- Finishing eliminating 'protobuf' argument from the API ]
+[ - Lose it in 'serialize-object-to-stream' and 'deserialize-object-from-stream']
+[ - Rename it to 'trace' in '(de)serialize-object' and 'object-size', ]
+[ make it be the last supplied argument ]
+[ - Fix up the '(de)serialize-object' and 'object-size' generators, too ]
+[ - Apply the same fix to 'print-text-format' ]
+[ - Then make the compatibility API actuallty work ]
+
+[- Implement 'parse-text-format' ]
