Oh, right. I guess in the following function, S would be a 
sequence if fun returned always false, as long as a != b.

bool fun(S, E : ElementType!S)(E a, E b)
{
     S s1, s2;

     s1.put(a);
     s1.put(b);

     s2.put(b);
     s2.put(a);

     return s1 == s2; // S is a sequence, if always returns false
                      // S is a set, if always returns true
}

So, if S is an associative array, fun can (and most likely will) 
return true. Good that it's not called a sequence then. It would 
be confusing if the meaning of the terms matched only 99% of the 
time.
