Another nice thing about having a next() built-in is that it makes getting the first item of a generator expression a lot more elegant, IMHO.

I think this:

next(item for item in items if item > 3)

is a lot clearer than this:

(item for item in items if item > 3).next()

or alternatives that would break this into multiple statements.

[inspired by a recent python-list question]
