Description

The Python Avro libraries don't actually have a proper JSON decoder or encoder, because they don't handle the type-hinting for unions properly.

The Python avro.io library should provide a pair of StrictJsonEncoder,StrictJsonDecoder} classes that correctly include (and decode) the type hints when the schema expects a union.

Jonathan Coveney raised this concern on the Avro User mailing list.
