This should be sufficiently short for people to fix the problem. I'd 
definitely say the code is valid: 
--------------------- 
template <typename _Iterator, typename _Sequence> struct S { 
    template<typename _Other> 
    bool foo(const S<_Other, _Sequence> &) {return false;}; 
}; 
 
template <typename _Sequence> struct X { 
    template<typename _Iterator> 
    void unrelated(const S<_Iterator, _Sequence>& __x); 
}; 
 
template<typename T> struct map : X<map<T> > { 
    typedef S<int, map> iterator; 
    void clear() { iterator().foo(iterator()); } 
}; 
 
template<typename T> struct scope { 
    map<T> undo; 
    void push () { undo.clear (); } 
}; 
 
struct A {}; 
struct B {}; 
 
template class scope<A>; 
template class scope<B>; 
------------------------
