New submission from Peter Farson:
Here's an example:
I'd like to be able to reverse a list for iterating...
for i in range(10).reverse()
This could work if reverse method returned self, but currently it
doesn't return anything. I think the overhead is slight and worth it.

Christian Heimes added the comment:
No, it's too confusing for users and it might hide bugs. The core types
either change an object in place and return None *OR* the method returns
a modified object. It's a design decision we won't change.
In your case you can use the reversed(range(10))
