There is no funcdamental problem with adding lexical scoping.
There is a slight problem with doing it in a way that doesn't
break existing code. Some libraries actually rely on
dynamic binding (e.g. Ogre, the documentation, parts of the
compiler...), so we can't just replace dynamic by lexical.
We would have to have access to both systems (like common
Lisp, Perl, etc).
