It is amusing that this works. define does not take type specifications for its arguments, as opposed to define-music-function and define-scheme-function. What happens is that (ly:duration? ly:duration?) is called as the first statement in the function. It checks whether ly:duration? is a duration and returns #f since it is actually a function instead. You do this several times. I'll look at the rest later. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
