SwitchSerializer is feature that let you more easely permorm serialization switch between classes that has one supper.
I used it in my projects very often, so I decided to publish it here

No tests, you clearly didn't even try to build this, and this seems like an overly specialized variant of what could be a more general keyed dispatch serializer.

There's a vaguer want for generalized TypeSerializer to support keyed dispatch and structural dispatch, but seeing this I think anything like that would make more sense as a fresh start.
