It would merely require using the same music expression more than once
without copying it.  Music expressions are frontend material.  I am not
really comfortable messing with them.  Now it is true that if you put
stuff in a music variable and access this using \var, you get a copy.
And music functions in general are not expected to worry about stomping
over their arguments destructively because of that.

But I still have a hard time believing that every Music variable is
guaranteed to never have anybody ever look at it again once it has been
seen by an iterator once.
