Does this work if test is in a different module from main?

struct test

}

void main()
{
        test t1 = test();
        test t2 = test();
        auto n = t1 * t2;
        assert(n == 3);
}

And it appears it does.

This changes the dynamics. opMul is not a template, which is important for  
classes.

This also works, and if encapsulated into a mixin, will be a drop-in fix  
for existing opMul and friends code:

struct test
{
   alias opBinary(string op: "*") = blah; // to demonstrate it's not  
actually calling opMul because of old-style operators

   int blah(test other) {return 3;}
}

BTW, I don't know when template alias got so cool, but I like it :)
