This might work in 2.6 or .7, but I do not really know.
The next() builting was introduced in 2.6 so that *users* could write
item = next(someiter)
and have that work in 2.6+ and in 3.x without change.

Depends on your Python version. I recommend you use 3.2 unless you have
a reason or need to use something else.
