Feature or enhancement

Proposal:

There are several opportunities for speeding updataclasses._asdict_inner (and thereforeasdict) while maintaining the same underlying logic (including function signature and return values). My in-progress branch has ~18% speedup. Will open PR soon for scrutiny.

Has this already been discussed elsewhere?

No response given
