Awesome; thanks for doing the hard work on this. I started looking into
this myself, and quickly realized I was way over my head (and available
time to commit to it).

OK.

OK. I *might* be able to convince the guile maintainer to keep 1.8 just
for lilypond, but that also might mean that I'll end up having to
maintain guile 1.8 too.

Could you point me at a list of guile 2.0 bugs which are affecting
lilypond? Having that list handy would help me convince the guile
maintainer (and also Debian's release managers and security) that there
were valid reasons to keep guile 1.8 for another release of Debian.

Thanks again.
