@bfabry: In my small experience with this stuff specs is too "open" to allow conversions like this without hitting tons of problems down the road. Prolly better to limit yourself to a subset of specs, and maybe front all this will a small DSL that would avoid people to go wild with theirs spec

@mpenet yeah, I definitely wasn't planning on trying to create a "complete" spec->avroschema thing. just register arbitrary predicates against their avro conversion
