Optional argument declaration syntax conflicts with the use of anonymous lambda functions. Actually, I would expect the main problem to be the other way round: a lambda function used as a regular predicate gets confused with an actual argument. But since anonymous functions don't work with mandatory arguments, using them for optional arguments is not likely a good idea either. At any rate, the example is far too complex to sensibly "have a look". Can you reduce this to something smaller? -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
