Serialization isn't the only issue - you have to know how to deserialize as
well. I use JSON extensively in Mailman's REST API. For enums I always
encode them to just the member name, because I always know what enum class
will be used to deserialize them.
(TBH, I wish the json module had better hooks for extending both serialization
and deserialization of non-basic types.)
