> The OP sample still fails.

The OP sample cannot compile, because ConcatAssignExp will try to instantiate
opOpAssign!("~"). Correct sample code is:

class C
{
   void concatAssign(C other) { }
   void concatAssign(int other) { } // to demonstrate overloading

   template opOpAssign(string s) if (s == "~")  // FIXED
   { alias concatAssign opOpAssign; }
}
void main()
{
   auto c = new C;
   c.opOpAssign!"~"(c); // works
   c.opOpAssign!"~"(1); // works
   c ~= 1; // line 15
}

So, this bug is already fixed.
