This closure strategy sounds fine, no?  It's what I would do, I think,
if I understand the problem correctly.

I thought that you were saying that lilypond code could reference and
set Scheme lexical variables.  I was also under the impression that
lilypond code could define lexical variables.  If neither of these are
true, then closures sound like a fine solution to me.

Am I missing something?  It has been a long thread :)
