[Python-ideas] Introduce collections.Reiterable

[Neil Girdhar]

Well, generators are iterable, but if you write a function like:

def f(s):
     for x in s:
             do_something(x)
     for x in s:
             do_something_else(x)

x should not be a generator.  I am proposing adding a function to itertools
like auto_reiterable that would take s and give you an reiterable in the
most efficient way possible.
