Lol, that's kinda an interesting idea:

     struct var(T, T def) {
         T payload = def;
         alias payload this;
     }

     alias var!(float,  0.0f) Float;
     alias var!(double, 0.0)  Double;
     alias var!(real,   0.0)  Real;
     alias var!(char,   ' ')  Char;

     void main() {
         Float f;
         assert(f == 0.0f);
     }

a Hack though, since it doesn't work with 'auto'. I still think 
it should be the other way around, and this should be used to 
Default to NaN.
