that's strange. Can you give an exact example?

 a b c #(..stuff..)

easily doesn't do what you'd expect. The idea is that we will move to
the following syntax

   note-\stuff-\morestuff-\evenmorestuff

if you want to use #(..) in stead of \stuff, you have to use
ly:export, i.e.

   note-#(ly:export (make-some-music .. ) )


just another note: I gather that this is something for the ancient
notation, while I'm used to clusters being a modern music thing (a
chord with all notes between some range). Is this the same, or are
there two kinds of clusters. If yes, shouldn't we distinguish them by
name?
