I believe that's the best choice even long term. `real` is 
supposed to represent the largest natively supported FP type by 
the underlying ISA. In WebAssembly that's f64, so there's no need 
emulate anything. Of course, people who need wider 
integer/fixed/floating types can use third-party libraries for 
There are other platforms where D's real type is the same as 
double, so I don't see a reason to worry.
