I apologize for not making myself clear. But that's part of what I meant, yes: we should preserve the existing behavior of times=-1 when passed in by position or by keyword. However, we should *also* add a deprecation warning when passing times=-1 by keyword, suggesting that they use times=None instead. The idea is that we could eventually remove the PyTuple_Size check and make times=-1 always behave like times=0. In practice it'd be okay with me if we never did, or at least not until Python 4.
So we only add deprecation warning to only times=-1 via keyword or for all negative numbers to times via keyword? I mean, what about:
from itertools import repeat list(repeat('a', times=-2)) Traceback (most recent call last): File "<stdin>", line 1, in <module> OverflowError: Python int too large to convert to C ssize_t
Deprecation warning or not?
