[Python-ideas] Implement comparison operators for range objects

[Guido van Rossum]

We've been bikeshedding long enough. I propose to do the following to
range() in Python 3.3:

- add read-only attributes .start, .step, .stop
- add slicing such that it normalizes .stop to .start + the right
multiple of .step
- add __eq__ and __hash__ which compare by .start, .step, .stop

And no more.
