Prohibit placeholders in partial keywords #125028
Description
Feature or enhancement
Proposal:
This has already been pointed out to me, but I could not see possible use cases at a time and they came with a slight delay.
There is a possibility for functionality that makes use of keyword Placeholders to be needed in the future.
Realistic use case is the ability to use map with keyword arguments. See: #119793 (comment)
import functools
functools.partial(lambda a: None, a=functools.Placeholder)
# TypeError("keyword Placeholders are not allowed")Has this already been discussed elsewhere?

I panicked and closed this prematurely. Apologies for the mess.
