pathlib *isn't* TOOWTDI, since it takes almost 10 milliseconds to import
it, and it introduces a higher level object-oriented abstraction that's
genuinely distracting when you're using Python as a replacement for shell
scripting.

While lazy imports could likely help with the import time problem (since
6.5 of those milliseconds are from importing fnmatch), I think there's also
a legitimate argument for a two tier system here, where we say "If you
can't handle your filesystem manipulation task with just open, dirname,
abspath, and joinpath, then reach for the higher level pathlib abstraction".

Cheers,
Nick.
