Unfortunately, their solution isn't a pytest incantation, it's a
separate 'compileall' invocation they run on their source tree. I'm
not sure how you'd convert this into a pytest feature, because I don't
think pytest always know which parts of your code are your code versus
which parts are supporting libraries.
