How about first getting C++/Scheme right?  As I already explained,
cleaning up the mess of layers and control flow will

a) give a better basis for judging that approach
b) make it easier to migrate individual layers to something else if
   desired

Take a look at Goops: it offers a lot of the things the C++ class system
does, with reasonable performance and much better reflection and
extensibility.  I am currently working on moving the property/event
system there, and one will have to see what the performance impact on
that will be.

It's all nice to throw all sort of language names into the ring, but as
long as the architecture of LilyPond is one incoherent mess, porting it
is not going to clean it up.
