I propose adding the ability to compare range objects using methods (e.g. range.issubrange) and/or regular operators. Example:

    In [56]: range(0, 10, 3).issubrange(range(10))

    Out[56]: True

    In [57]: range(0, 10, 3) <= range(10)

    Out[57]: True

    In [58]: range(10) <= range(0, 10, 3)

    Out[58]: False

I'll write a patch if you decide that this idea is worth implementing.
