You have to remember that an instantiated template creates a 
totally distinct type.

There are few different ways to face your problem, this is one of 
them:


import std.stdio;

class Foo(uint N) {
     Foo opBinary(string op, uint N2)(Foo!N2 rhs) const
     if (op == "*") {
         "calling Foo.*".writeln;
         return new Foo;
     }
}

class Bar: Foo!3 {}
class Baz: Foo!4 {}

void main() {
     auto bar = new Bar;
     auto baz = new Baz;
     auto foo = bar * baz;
}
