Eh, depends on what you're doing, I guess?

The alternative spelling is:
list(f for f in check_tests if is_python_file(f, directory))

... which I guess *is* shorter and skips the lambda. but, I suppose I have
some mild revulsion to seeing "f for f in ..." constructs.
If I ever tell you not to use a filter, feel free to cite this patch and
then just tell me to shut up. I apologize for any inconsistencies in my
style, real or imagined.
