Are we going to support ...

- ... "enums"? Enumerations that get checked properly are probably a
usability/security win.
- ... inner structs? (Side comment: protoc declares an inner struct/message
Foo::Bar as Foo_Bar + a typedef to allow Foo::Bar to be used, which is nice
since it allows Foo_Bar to be forward-declared.
- ... inner (nested) namespaces?
- ... importing other IDL files? (Side comment: The latest protobufs
distinguishes between "import" and "import public", which is nice.
Forward-declarability is required for this.)

(Protobufs support all of these. Probably some of my questions have been
answered somewhere, but I'm too lazy to dig through design docs at the moment.)
