Sorry, I had a couple responses partially written but never finished.

If we were doing it from scratch I would suggest using longer names. At the
least I would still suggest using "ascii" or "asciiword" instead of "aword".

This does bring up another idea. Using the ctype names. They could be named
asciiword, alphaword, alnumword. Frankly I don't think this is any nicer than
numword anyways.

I tried thinking of better words for this and couldn't think of any. The only
other word for a hyphenated word I could think of is probably "compound" and
the word for parts of a compound word is "lexeme", but that's certainly not
going to be clearer (and technically it's not quite right anyway).

So in short I would still suggest using "ascii" instead of just "a" but
otherwise I think your suggestion is best.
