[New-bugs-announce] [issue20232] Argument Clinic NULL default falsely implies None acceptability

[Ryan Smith-Roberts]

New submission from Ryan Smith-Roberts:

When one specifies a default of NULL, the generated signature doc indicates a default of None. However, if the user actually supplies None, perhaps as a placeholder in a positional-only call, C code which only checks for NULL will fail inappropriately.

The solution may be to convert a None object to a null pointer in the wrapper.
