Ah, yes, I see it now, thanks. It's a good change, then: the new code
is more clear. I wonder why we do that, tho:
the previous code didn't have a comment, so I'm left guessing that maybe
it's that we don't want to advertise as "will stop when exiting foo"
a function which we're exiting?

Sounds right.

Good point.
