It's useful to have a cartesian product of ranges, like a std.range.product:

See also the handy design of Python itertools.product:

http://docs.python.org/library/itertools.html#itertools.product

itertools.product(*iterables[, repeat]) 
Cartesian product of input iterables.

product('ABCD', 'xy') --> Ax Ay Bx By Cx Cy Dx Dy
product(range(2), repeat=3) --> 000 001 010 011 100 101 110 111
