I don't think so, but neither is assignment to association list members I think. They were some special case once written as variable #'field #'field = #value and syntax variable.field.field = #value was introduced way before that kind of syntax was used for context subproperties and was only useful for setting rather than retrieving. So this is heavily un(der)documented and it doesn't help that it's not quite clear how much more can sensibly actually be achieved here. As you noticed, the currently supported set is not overly consistent. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
