Hi,
This is a very rough draft, opening to see if @jcrist will be open for this feature/approach.
It addresses #656 and my own #541 - allowing to decode data representing a tagged struct subclass in place of the super class.
This feature prevents me from switching to msgspec in my ast library, but should be generally very usable for any tree-like structure/messages.
As of time of writing, in order for this PR to be complete, at least the following has to be handled:
allow_tagged_struct_subtypes
kwarg into json, msg pack decodersallow_tagged_struct_subtypes
, so it will not honor the flag after decoder (type node) is cached for the first time
