The big difference is in assignments:

   real a, b;
   creal x = a + b*1.0i;
   auto y = Complex!real(a, b);

   // Also, this doesn't work with current complex types, because
   // creal.re and creal.im aren't lvalues:
   Complex!real z;
   z.re = a;
   z.im = b;

But it's not a problem, really. Since Complex!T is binary compatible 
with the current complex types I can just insert a few casts here and 
there. I just wanted to make sure I wouldn't have to go back to creal & 
co later.
