Seems rather straightforward. You'd put an appropriate 'syntax property on the music function definition (possibly by allowing a :syntax keyword argument in define-music-function, defaulting to 'SequentialMusic or something else that makes sense), the lexer would check it and return an appropriately different token that would make the parser execute it without finishing the current time step first, using pretty much the same parser for argument lists as normal music functions do. -- David Kastrup _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
