It's great that you show so much patience with rank beginners in
LilyPond.
Gentlemen, please.
It's obvious and well-known that few people know LilyPond's design and
inner workings as well as David, so if he raises concerns about a design
question, it's a pretty safe bet that there's a bona fide issue at hand.
But it's also obvious that LilyPond can only benefit from motivated
development newcomers, especially in this case where the "newcomer" is
actually a veteran power-user who knows the strengths and current
limitations of LilyPond very well.
So can we please try to avoid sarcasm and try to assume best intent on
the respective other's side? Having met both of you, I am sure this
assumption is actually quite reasonable.
