Using simple regexp substitution with Perl, Python or whichever scripting 
language you like is quite fragile, because regular expressions alone are 
not enough to parse LilyPond input format.

Currently Scheme is the only way to do it cleanly.  Best would be 
implementing lambda calculus in ly language itself; I hope it's possible 
with writing a few music functions in Scheme.  People at the GRAME in Lyon 
have already thought about lambda calculus usage in music notation, their 
articles is a good starting point for implementing these ideas in LilyPond. 
 I don't have time to do this myself before March, though.

Best,
John
