And there are many cases where the default grouping by beat structure is pretty much what you want. In the worst case one can simply group the notes manually, which is still much faster than doing lots of different tuplets and hiding the Brackets (if you do a piece that frequently changes between division 2 and division 3 this takes a stupid amount of time!)
You could easily write your own music function to write in division 3. \inThree {c8 c c} Or \"in3"{c8 c c} Or \in³{c8 c c} Your function could do whatever you would like to do about hiding brackets or anything else you wanted to do. And it wouldn't require rewriting LilyPond's parser. Or hardwire non-conventional notation into LilyPond's core. Carl
