Re: [Caml-list] [ANN] ppx_protobuf

Nice, great work!

I'm not actually a huge fan of mixing type definitions and the protocols
they can be encoded/decoded from.  How hard would it be to take a module
definition accessors on a type and produce a new module with
encode/decode functions?  That way I could create JSON, XML, Protobufs,
etc modules from one module.

Just an idea!
