There is not a goal per se to move stuff from C++ to Scheme, but
rather to expose relevant (C++) interfaces to Scheme so people can
write the extensions in Scheme if they want.
Come to think of it, it's actually a neat project to write a Scheme
interface to engravers. It would be a suitably sized project for me
to do over the christmas/newyear holidays.

I have a different viewpoint. I am mystified by the desire of some
people to mess with the most complicated parts of the program, without
having the knowledge to pull that. It's possible to do that, but it
requires a lot of skill in absording a lot of code quickly. From a
didactic point of view, I don't think it is a good way to starting
learning how things work. It's better start with small projects,
small improvements, and then gradually extend the scope of the changes
you make, to keep step with the improved understanding of the
infrastructure of the program, while you make changes.

As it is, the inner circle is very small, and I am a large part of that circle.
Here is the problem from my perspective: I don't have a lot of time to
spend on this. If you want to ask me questions, they had better be few
and very well posed, because I don't have the time or energy to deal
with a barrage of questions, especially if there is no pay-off for me
in terms usable patches to the LilyPond core.
