So Apple has crippled their Python (e.g., how do you use your own NumPy
with the system Python now if you can't load it?). I guess you could pay
$100 a year, but that seems silly just for code I run locally too. But I
hear that apparently the standard operating procedure is to just build
your own Python anyways for such use cases (or use python.org too).

What's funny is that they don't require signed .py files as well since
they're just as arbitrary code as any .so modules.
