[issue20232] Argument Clinic NULL default falsely implies None acceptability

[Ryan Smith-Roberts]

Ryan Smith-Roberts added the comment:

sha1 is Vajrasky's module. I have a much more complicated example (and Vajrasky and I just both posted on python-dev separately about this issue):

sockobj.sendmsg(buffers[, ancdata[, flags[, address]]])
->
sockobj.sendmsg(buffers, ancdata=None, flags=0, address=None)

Here ancdata wants an iterator and address a tuple, and the existing function expects NULL when these are absent. This is what we've been indirectly discussing via email as well.

Aaand I just realized that I should set py_default to []?
