Yes, that is true.  xNote is a music function, not an operator.

Yes, it is.  But the function still works properly without the braces.

I agree that it might be confusing.  I'd be fine to have a postfix operator
that would work, as well as a music function that takes a sequence of notes.

But I don't know how to make that happen.  That would require changes to the
parser, and I've never been successful with trying to make changes to the
parser.

If there's somebody who could help talk me through the process, I'd be
willing to learn.

Otherwise, I think we're stuck with a music function, not a postfix
operator, for right now.

And if we're ever going to move it to a postfix operator (which is one of
the goals of the GLISS project), now is the time, before we get a strong
codebase of music function applications.

Thanks,
