template <class Key, class T, class Comp, class Alloc> bool operator<=(const map<Key,T,Comp,Alloc>& x, const map<Key,T,Comp,Alloc>& y); template <class Key, class T, class Comp, class Alloc> bool operator<=(const multimap<Key,T,Comp,Alloc>& x, const multimap<Key,T,Comp,Alloc>& y);

operator is
equivalent to ! (y
