That sounds more like something I should be confessing. The #/$ dichotomy ($ previously was implemented via ly:export causing a lot of problems) and define-scheme-function/define-void-function were designed and implemented and to a good degree documented by me. It may well be that some aspects where decisions had to be made that were reasonably consistent with expectations and previous behavior did not really make it into proper documentation. The code most certainly has seen quite more wholesale rewrites and refactoring than the documentation: the documentation has mostly just seen amendments additions. Consequently, it tends to be more patchwork and less consistent in style and organization. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
