This is because of Issue 7549. Not a duplicate as library have to workaround
compiler bugs and work correct.

module program;

import std.stdio;
import std.traits;

class a {}
class b {}

int f1 (a o) { return 1; }
string f1 (b o) { return 2; }

void main () {
  a a1 = new a();
  b b1 = new b();

  writeln(a1.f1()); // 1
  writeln(b1.f1()); // 2

  typeof(a1.f1()) v1; // int
  typeof(b1.f1()) v2; // string

  ReturnType!(a1.f1) v2; // Error: no property 'f1' for type 'program.a'
 // Error: ReturnType!(__error) is used as a type

}

I am sorry for such bad description but it seems to me that there are multiple
bugs here and I am not sure where the problem is - or even if there is one.
Free free to provide a better description =)
