Since something different happens at runtime, it needs a different syntax. At some point we had \set Foo.Bar \override #'x = #y syntax for this, but it was deemed to confusing, so we gave it a different syntax. -- Han-Wen Nienhuys - han...@xs4all.nl - http://www.xs4all.nl/~hanwen _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
