I think the dict constructor is already a bit too complicated, and
would prefer that it be a separate classmethod, such as
dict.zip(keys, values=itertools.repeat(None))
The default argument on values should finish the replacement of
dict.fromkeys functionality that sets and defaultdicts began.

I think it has to do better (at least by eliminating the temporary zip
object) to be worthwhile; the do-it-yourself alternative is pretty
short.
>>> # from itertools import izip as zip
>>> def dictz(keys, values): return dict(zip(keys,values))
