A number of things wrong with it. For one, it's not well-defined just when the variable is available. For another, there is no point in using a string? argument when you actually need a symbol? argument. And worst of all, the command does not bother creating a copy, so any destructive manipulations on one variable (like \relative, \transpose, and others) will magically appear in the other variable. Not particularly enthused about the side effect in the middle of music either: people might expect \tag to have an effect on whether or not some sequence is defined in some branch, but it won't. But that's not all that dissimilar to surprises about \relative and \tag . -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
