Thanks for your effort. It's very much needed and appreciated.

Better encapsulation is definitely needed, and using C++ allows the
compiler to enforce this encapsulation, instead of just grepping
manually to make sure each private isn't used outside of
getters/setters.
For example, I was trying to write some code to make the mark be
window-local and not buffer-local, just like the point. And it's hard
to see all uses of point wrt window-point, because of insufficient
encapsulation.
