It's incredible how many people jump in to point out that it's
possible to rewrite that (no, sorry, file.readlines() might need
more than your available RAM and is not the same), when I just tried
to say that I miss assigning and testing with one statement.

And again, before another round of people start pointing at me,
yes, Python's cookbook receipt 1.9 suggests another way to do that,
like wrapping in a class or using list comprehensions. Thanks in
advance for pointing out this too.
