Comment (by vdelecroix):
I am strongly against that this ticket is being merge now. We are far from
having the Python 3 switch tomorrow (is it even a blocker for sage-6.3?).
It will slow down everything. `xrange` is faster by 40% on lists of size
100:
{{{
sage: timeit("for i in xrange(100):\n for j in xrange(100): pass")
625 loops, best of 3: 362 µs per loop
sage: timeit("for i in range(100):\n for j in range(100): pass")
625 loops, best of 3: 501 µs per loop
}}}
And there are many of them in Sage source code.
