In the first one, you check typeof, but not in the second one.
writeln(isInstanceOf!(Nullable, typeof(f3))); // true
The template argument there was T
The following result doesn't make sense to me... how does
isInstanceOf return false?
```
import std.traits;
import std.stdio;
import std.typecons;
auto f(T)(T t){
return Nullable!T(t);
}
void main(){
auto f3 = f(3);
writeln(typeof(f3).stringof);
