That's the idea, yes.

I'll let you guys decide together. I stated my preference, but I have
better things to worry about.

The lexically scoped `yield' is OK. But the global (defmacro yield ...)
is not (tho, I'm OK with keeping it if wrapped in (unless (fboundp
'yield) ...)).

I know, but this one is out of the question. All globally-visible names
need to be namespace-clean. So it can be `gen-next'.

I know, but being globally visible, this is also out of the question: it
requires something with a "gen-" or at least some "generator" in its
name somewhere.

But it doesn't say we're iterating on your particular kind of iteratable
construct.
[ BTW: regardless of namespace cleanliness, I don't find "iterating"
above to be a good choice, because "x" doesn't "iterate y".
The "cl-loop" doesn't do anything else than iterate, so "iterating" is
almost necessarily a misnomer in there. From an English language
point of view, I'd expect something more like "for x generated-by y"
or "for x in-generator y" or "for x in y". ]
