The AC doesn't support properly positional-or-keyword arguments per default #125954
Closed as not planned
Description
Feature or enhancement
Proposal:
Currently, #125917 makes only last argument of the reduce to be positional-or-keyword. But with:
_functools.reduce
function as func: object
iterable as seq: object
initial as result: object(c_default="NULL") = _functools._initial_missing
Apply a function of two arguments cumulatively to an iterable, from left to right.
[...]
it can't built the interpreter:
$ make -s

Has this already been discussed elsewhere?
