Re: lily rO><Or!

I was wondering...

if you cannot optimize the code itself very much. maybe it is possible 
to improve the way Lilypond parses the ly file.

When I am editing and tweaking a file, I need to change one little 
thing and recompile it.
As far as I can see it, lilypond then always runs the complete file 
from scratch...

Maybe it is possible to provide lilypond with a kind of diff function 
that enables it to determine the changes and change only what is 
necessary ?
(by saving states for example...) Or is this impossible ?

If this could work it could mean quite a speed improvement...
