[Python-3000] Is this really a SyntaxError?

[Georg Brandl]

Someone just wrote to the docs mailing list and reported that the itertools
documentation for Py3k contains this recipe:

def grouper(n, iterable, fillvalue=None):
     args = [iter(iterable)] * n
     return zip_longest(*args, fillvalue=fillvalue)

It is currently a syntax error in 3k. There's also a test for it in
test_keywordonlyarg.py, however, I can currently see no reason why
it should be disallowed.

Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
