Mostly I agree with Steven on relative preference:
itertools.zip_strict() +1
zip.strict() +0.5
zip(mode='strict') +0
zip(strict=True) -0.5
For me:
* zip(strict=True) +1
* zip(mode='strict') -0
* itertools.zip_strict() -0.5
* zip.strict() -1 (but really, I'd like to make this -1e10)
Since we're posting:
itertools.zip_strict() +1
zip.strict() +0.1
zip(strict=True) -0.5
zip(mode='strict') -1
itertools.zip_strict() +1
zip.strict() +0
zip(strict=True) -0
zip(mode='strict') -1
I don't particularly care for "strict", though. It doesn't seem specific enough, and doesn't say
"they iterators must return the same number of items" to me. I sort of liked "equal"
better, but not so much to make a big stink about it.
Also: The PEP says "At most one additional item may be consumed from one of the iterators when compared
to normalzip usage." I think this should be prefaced with "If ValueError is raised ...".
Also, why does it say "at most one additional item". How could it ever be less than one?
