[Python-Dev] iterator API in Py3.0

[Michael Hoffman]

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.
