Re: Some wild considerations and a question

Are you talking about reimplementing LilyPond from scratch?

I'm happy with Scheme, as a programmer. It's the Guile implementation 
that causes the performance issue with Guile 2, not the Scheme 
languages. Perhaps it's just that with advanced tools one requires 
advanced knowledge. As with anything.

Here's my two cents worth. For modern implementations, you could inquire 
as to how Dorico is implemented. [May be proprietary information.]

Being a very heavy user of LilyPond, what I don't like is twofold, a) 
it's compiled, and the compilation takes a very long time, and b) its 
completely single threaded so having a really grunty machine makes very 
little difference to a). Whereas programs like Dorico hold in memory 
presumably and changes even to large scores are instant. They would be 
the biggest changes I would like, but of course necessitating complete 
rewrite. Seems unlikely to me. But after years of LilyPond I am at the 
point where I need to go to Dorico because I can't afford minutes of 
wait time to tweak a slur or make other micro changes (even with the 
typesetting on/off commands my scores are so complex the compiles are long).
