Speed up dataclasses._asdict_inner #114087
Description
Feature or enhancement
Proposal:
There are several opportunities for speeding up dataclasses._asdict_inner (and therefore asdict) 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
