There is actually one example of a naturally occurring meter, meaning it is
used regularly, where such a sub-beaming might be useful, namely, a form of the
Čoček in 9/8, 9 = 2+2+2+3, where 3 = 1+2. I wrote it as 2+2+2+1+2, but it would
be nice to write it as 2+2+2+(1+2).
If I write
\time 9/8
\set beatStructure = 2,2,2,3
\set subdivideBeams = ##t
then it ends up with all 2 = 1+1, and 3 = 1+1+1.
So such examples may occur even if there is not a composer trying to do
something special.
