Okay.  That eager evaluation of lengths by the iterators also frustrated my 
attempt at a \RestUntil function (to fill the tuba part, for example, with 
rests until the next tempo change) so we might change that someday.

I see.  It is not very likely that anyone refers to tremolo-type of the Music, 
so possible tweaking does not seem enough reason to keep it.
