At the moment, built in objects such as lists don't support the slice notaton l[a:b:c]. Would there be support for including this in Python 2.3? If so, what would be the necessary procedure? Would this require a PEP? Alex Martelli has offered to do the code, if someone will champion the work. I'm happy to do this, but I don't have commit privileges, so it would require someone else to actually commit any changes. I presume that the correct approach would be to submit the changes as a patch to SourceForge?

I would be happy to help on this one either in the design stage, code review, or writing the unittests and docs.

Maybe we should also address the str/getitem/slice bug www.python.org/sf/473985 and kill two birds with one stone (or tie two swallows to one coconut or some such).
