Just like getattr, two-argument next(iter, sentinel) returns sentinel if StopException is caught. +1. I've written a number of pieces of code where this would have made things neater. Just about any place where I've used .next() explicitly, in fact -- it always seems awkward having to deal with StopIteration.
Indeed, you almost always have to have a try-except StopIteration- wrapper around "manual" calls to .next(). In many of these cases, a default value would make things nicer: +1.
