Yes! RedHat, RedHat! (hint hint)

I know -- I'm implying that people translate 4 -> f, 5 -> g , etc. in
their heads. Extension is left as excercise for the reader. I'd do it
by catching Rest_req's

I hope that someone else will take over this part of the patch.
Similar to mapping pitches and numbers in your head, implementing the
details is not that difficult, but it's not a challenge for me, and
rather tedious as well.

I'll have a good night's sleep over new syntax.
