[pypy-issue] [issue1677] itertools.product slower than nested fors

[Armin Rigo]

Try again with tomorrow's build: http://buildbot.pypy.org/nightly/trunk/ .  I
hope it should be a bit faster, but I don't know how much.

Note that our goal is to ensure that itertools is not massively slower than
plain Python, but we don't really care about making it exactly as fast (or
faster) as plain Python.  As long as it's not massively slower, it's fine.  (At
least I don't agree with you about whether a) or b) is easier to read :-)
