Make dataclasses construct automatic docstrings lazily #144764
Description
Feature or enhancement
Proposal:
Profiling import time on a client project revealed ~30% of the time for dataclasses was spent creating the docstring, mostly because inspect.signature() is costly. In most executions, this time is wasted, as such automated docstrings are rarely referred to during normal execution.
It’s possible to make the docstring generation lazy by writing a descriptor class.
