Any and all opinions welcomed, I'm chickening out and sitting firmly
on the fence.
According to the article itself, "it relies in an implementation detail
(the order the zip function iterates over the arrays) to work." Then
again, the article also points to the official docs that says that this
implementation detail is guaranteed.
So it's no worse than depending on some weird but *documented* corner of
the IEEE-754 or POSIX spec.
In fact, this is also a code recipe found in the itertools
documentation. The official docs don't just guarantee it; they
*recommend* it.
def grouper(iterable, n, fillvalue=None):
"Collect data into fixed-length chunks or blocks"
# grouper('ABCDEFG', 3, 'x') --> ABC DEF Gxx"
args = [iter(iterable)] * n
return zip_longest(*args, fillvalue=fillvalue)

Which is available here https://pypi.python.org/pypi/more-itertools
along with many other goodies.
