Last time I looked it broke because LilyPond uses the symbol "void" as a music function and the 1.8 implementation is broken enough that it then evaluates it somewhere. I am afraid you need to stick with macros. On the plus side, their behavior is a lot more clear since they act only when called, not through some pattern matching. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
