The problem with guile 2.0 is that it includes many major changes (compiled 
code, new macro handling, new garbage collection, completely new 
string/unicode handling, etc.), which also require major code changes and 
restructuring. Lilypond, however, has not been tested AT ALL with the new 
version yet. Currently, Ian is trying to make lilypond compile and make the 
basics work with guile 2.0.

Guile is not just some additional extension package that lilypond uses, where 
an update should be mostly painless. Lilyond uses Guile at its very core, and 
large parts of lilypond are implemented in guile, so an update to guile 2.0 
means replacing the very core of lilypond.

I don't think you want to play the guinea pig for such a guile 2.0 switch.

That's like switching to a completely untested, unstable kernel version 
shortly before a distribution release.

Cheers,
Reinhold
