Allowing negative `maxsplit` in `str.split`
Here's something that I would want now: An ability to give a negative `maxsplit` argument to `str.split`, to make it start splitting from the end of the string. For example, right now I wanted to be able to separate a module's name 'hello.world.meow' to ['hello.world', 'meow'] without knowing how many dots would be in the name. If I could give a `maxsplit` of -1 to achieve this, it would be nice. What do you think? Ram. (Please `cc` any replies to me if you can, thanks.)

What's wrong with 'hello.world.meow'.rsplit(maxsplit=1) ? Cheers, Chris -- http://blog.rebertia.com

What a noob I am, I didn't know that existed. Thanks Chris. Ram.
