Crazies? :-) http://homepage.mac.com/sigfpe/Computing/peano.html
Having switched from C++ to Haskell (at least in my spare time) I thought I'd escaped that kind of type hackery but it seems to be following me...
The way I see, we are trying to come up with a clean way of providing type-level computations (ie, we use and extend the standard theory of HM type systems). C++ embedded a functional language in the type systems mostly by accident, whereas we do it on purpose.
