Believe me, I'm better known for premature pessimization then premature

It's no longer a matter of compilation times (I can live with that), but a
matter of the compiler no longer being able to handle it (running out of
memory, out of keys, etcetera). I've tried many other things first (/Zm,
splitting up source files, etcetera), but I'm beginning to believe that
meta-C++ is just not quite ready for the algorithmic complexity of some of
my meta-code.

I've started reaching for the preprocessor a lot lately, and I'm now writing
a blend of template code and preprocessor code that is quite elegant, albeit
completely unreadable ;).

It does compile a lot faster fortunately.
