Thanks for the improved version!  I'm not exactly fluent in Scheme -- combine 
that with needing to work out which of Lilypond's variable types to use, and 
it's not easy to just come up with something on the spot.

I can see a number of potential issues -- e.g. if you have some parts that are 
written (in Lilypond) in concert pitch with both \transposition and \transpose 
statements, and some that are written in transposed pitch with a \transposition 
statement, things could get nasty.

But for my current use case, it's satisfactory.
