Re: Implement optional music function arguments (issue 5023044)

[Carl . D . Sorensen]

I'd be lying if I said I understood everything going on here, but I
think I get the gist.

I like moving this way!

I like the approach of simplifying things.

I like having optional predicates, and optional predicates with
defaults.

I will trust you that it is O(n) and that all the shift-reduce conflicts
have been resolved.

I'm not a parser expert, so it doesn't mean much coming from me, but I
think this looks good.
