Hi folks, I'm working on a custom serialization on top of cl-serializer. Some questions have come up: 1) Why aren't SERIALIZE and DESERIALIZE generic functions? I could just specialize them this way or augment them with auxiliary methods. 2) How am I supposed to make cl-serializer actually use my custom definer? Do I really need to define my own mapper? This would be quite unwieldy as I would have to always specify this mapper then which makes the whole point of the definer a bit moot since I had to write a wrapper for this anyway... 3) Is this the intended way to support custom types in cl-serializer? 4) What id space is intended for custom types? The one between +first-reserved-code+ and +last-reserved-code+? I also noticed that the definer 'serializer-deserializer' isn't exported.
