I have no real objection to this, and in fact have already implemented
some of it in BarFly. However, while it is perfectly easy for display
programs to implement, when it comes to playing abc that's another story!
One immediate problem is that there are many tunes out there which are
(incorrectly) written as:
|: ,,, |1 ... :|2 ... :| ...
BarFly (and probably other players too) will patch this up and let
it play correctly because it _knows_ that only two repeats are possible.
Once higher numbers of repeats become available this has to be flagged
as an error (missing third repeat).
I've found it quite difficult to get all the alternate ending possibilities
to play correctly. Not that any of this is an argument against the
proposal, just that it may take a while for players to catch up with
the standard if it is incorporated.
