Hi Jacques,
I split my replies to address different aspects separately.
This one about scheme/guile

Doing more in C++ will probably speed up, though then this
C++-functionality is not longer accessible for the user.
Unless you provide entrance-hooks in said C++-code which probably will
lower speed again.
Currently the melange of scheme-guile/C++ is very close. Switching to
another extension language will mean to rewrite mostly anything,
loosing a plethora of user-code like in oll and LSR and on this list.
Furthermore, speaking only for myself, I'm not a programmer, I have
not even owned a computer for the first three decades of my life.
After discovering LilyPond I learned guile to let LilyPond do what I
want it to do. This was work, yes, and I'm still learning. Though, I
will not have the energy and motivation to learn a different language
to extend LilyPond.
Imho, the main problem users have with guile in LilyPond is not guile
itself, but the poorly documented interplay between them.
Cheers,
Harm
