[Sergey Fedoseev]

New submission from Sergey Fedoseev <fedoseev.sergey at gmail.com>:

zip() shadows TypeError raised in __iter__() of source iterable:

In [21]: class Iterable:
    ...:     def __init__(self, n):
    ...:         self.n = n
    ...:     def __iter__(self):
    ...:         return iter(range(self.n))
    ...:     

In [22]: zip(Iterable('one'))
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-22-66835be83afa> in <module>()
----> 1 zip(Iterable('one'))

TypeError: zip argument #1 must support iteration
