My personal take on this would be that moving towards less reliance of the lexer on starting conditions (in particular quirky ones like this) would be desirable, even if it renders some previously valid input relying on such fine distinctions invalid, as long as there are easily understandable replacements. -- David Kastrup _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond
