I think Pro #2 answers Con #2, and dittos for #3's (in addition to some
implementation issues with speeding up reduce that way). But anyway,
yes, these _are_ the considerations made pro & con on this thread.
Anyway, whence now -- a PEP? (Seems a bit too small for that). Or, do
I just submit the patch (to where -- builtins?) and let Guido pronounce?
