That error message is much more clear and the problem much better
defined than what you will get if you reassign to something like X.

The problem in this case is not that LilyPond will refuse, but rather
that it will proceed.

I don't think we can really do this for Scheme, so we'd lose the
Scheme/LilyPond equivalence of variables.
