I agree that this’d be great.

A Scheme function can unfold repeats (we’d need one for absolute mode and one 
for relative), and a Scheme function can comb through music of arbitrary length 
and attach things to it, so we’re about a half-day’s work away from a hack that 
doesn’t involve iterators.

If we’re gonna touch the C++ iterators, it’ll require more design strategy and 
will take more time.
