Same w/ specialisation:

// <foo>
namespace std {
  template <class T, class U>
  struct foo;

#ifdef __cplusplus2000
  template <class T>
  struct foo<T, int> {};

// (c) Dave Null 1999
#include <foo>

template <class U>
struct std::foo<int, U> {};

std::foo<int,int> foo_int_int;

That multi-methods easily break because of ambiguities when
two persons independently add overriding functions is well-
known in the OO community.
