There is a library around the C preprocessor in Boost, 
Boost.Preprocessor (or Boost.PP, depending on how you want to call it).

It allows to do very powerful things and it is the most advanced usage 
of the C preprocessor I've seen.

It is widely used by most Boost libraries.

Expressions, loops, scopes can already be done.
For classes, just use tuples.

Templates and memory management don't make much sense; IO can be done in 
terms of #warning or something like that.

You mean an implementation of C++, implemented as a post-processor over 
another compiler, that would add new features?

I believe this could be interesting, but mainly to fix deficiencies or 
to add future standard features not available in compilers yet.
