That's different than template metaprogramming.  I've found some
really interesting docs on this stuff.  Check out:
http://aszt.inf.elte.hu/~gsd/halado_cpp/ch06s06.html

There's alot to digest and I'm far from understanding all this stuff
especially the Boost MPL lambda calculus classes, but I wouldn't say
hashing a string at compile time is impossible yet although I'm
getting there.
