As an illustration: take a look at ly/property-init.ly. It contains dozens of commands that will cooperate with the new \once. All of them (well, the reverting commands don't, just because \once\revert is not [yet?] workable in general). That's its principal selling point.
And I don't want to hide that. It's much more important than testing that it will work with some custom-defined command. http://codereview.appspot.com/5322065/ _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
