[issue32321] functools.reduce has a redundant guard or needs a pure Python fallback

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

I just merged PR 8548. See the PR to the discussion. IMHO it's a nice enhancement to have a pure Python implementation:
https://github.com/python/cpython/pull/8548#issuecomment-433063178
(and the PR has been approved by 2 other core devs ;-))

But I'm against adding it to Python 3.7 as well, I rejected the backport: PR 10092.

I proposed the author to write another PR to refactor test_functools.py, but I don't think that it's worth it to keep this issue open just for that:

----------
resolution:  -> fixed
