Agreed. The function code must be compiled to use certain

The compiler could in theory examine the entire program to 
determine a type for the parameter but the separate compilation 
model would preclude it.

 Although if you used a template you could pull it off... I 
think... But you'd need the sources for that.

 void multiOut(T)(out T outType) {
   outType = 100;
 }

 int a;
 char b;

 multiOut(a);
 multiOut(b);

 assert(a == 100);
 assert(b == 100);
