Yes, but the question is: which of these two alternatives? I would vote
for fixing tp_call but Petr voted for an error.

For static types I either wouldn't bother at all, or only

Hi Montana,
As Cameron Simpson already pointed out, your query is off-topic for the
Python-Dev mailing list and should be taken to the Python-Ideas mailing
list, which is for speculative discussion of new designs.
Like Cameron, I've CCed Python-Ideas. Please send any follow-ups to that

Hello,
I have one implementation question about vectorcall which is not
specified in PEP 590: what should happen if a type implements vectorcall
(i.e. _Py_TPFLAGS_HAVE_VECTORCALL is set) but doesn't set tp_call (i.e.
tp_call == NULL)? I see the following possibilities:
