Speaking of new potential list methods, how about list.get(index, default=None) ala dict.get ? I'm sure this has must have come up at some point but can't find it ATM.
I believe it runs afoul of the moratorium, but a getitem() builtin might be a better idea (since it would then work for any class that implements __getitem__).
Maybe just extending operator.itemgetter with a "default" kwarg? Wouldn't run afoul the moratorium, and would be quite a nice extension to itemgetter. Though I'm not sure it's a very good idea for lists. Semantically, lists are to be iterated, not really to be indexed.
