+//   Every name first declared in a namespace is a member of that namespace. If

+//   function the friend class or function is a member of the innermost
+//   enclosing namespace.

+//   qualified lookup (3.4.3) until a matching declaration is provided in that
+//   namespace scope (either before or after the class definition granting
+//   friendship). If a friend function is called, its name may be found by the
+//   name lookup that considers functions from namespaces and classes
+//   associated with the types of the function arguments (3.4.2). If the name
+//   in a friend declaration is neither qualified nor a template-id and the
+//   declaration is a function or an elaborated-type-specifier, the lookup to
+//   determine whether the entity has been previously declared shall not
+//   consider any scopes outside the innermost enclosing namespace.
