All arguments determine the namespaces search for functions. This is called Koenig lookup (after Andrew Koenig, inventor of this mechanism), or argument-dependent lookup. It applies uniformly to all unqualified function calls, whether operator or not. As a result, you should not overload operators based only on types from std. Instead, any operator you overload should involve one of your own types as well. It is an error to extend namespace std in an application.
