Sorry, I wasn't thinking properly when I typed that. (Haven't actually tried
to implement this yet.)
The second argument would need to be a "name", so a string/macro/diversion.
Attempting to iterate over an undefined one would probably throw a "mac"
warning. Attempting to iterate over a request would be rejected with an
error.

I'm starting to remember what I wanted the really-a-glyph predicate for.
See bug #63354. There's a lot to it.

Ahhh. No worries. :)
