Example code not quoted: it demonstrated a limitedly useful circumvention rather than the problem. One straightforward fix would be to provide for supporting an event-list? predicate that would then deliver an arbitrary-length (including zero) list of post-events. Another somewhat more cumbersome way would be to allow the PostEvents container music type (used in some restricted manners inside of the parser) to package multiple events also for post-event function arguments. However, that would likely complicate matters for the user since it might make that music event pop up in a number of places where it's never seen before.
For better or worse, this issue here is only about allowing bare rhythmic durations, previously allowed only inside of music sequences, as proper function arguments.
