If not you, then who should do it?

Python is open source and written by volunteers. If you want something done,
there are only four possibilities:

- you do it yourself;

- you wait as long as it takes for somebody else to do it;

- you pay somebody to do it;

- or it doesn't get done.

If you're not willing or able to do the work yourself, does that help you
understand why we don't use NFA?

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure
enough, things got worse.
