What about scoped using directive (or using declaration)?

{ // begin code using namespaces

   using namespace std;
   using namespace std::placeholders;
   vector<shared_ptr<SomeClass>> vec;
   for_each(vec.begin(), vec.end(), bind(&shared_ptr<SomeClass>::get, _1,
bind(&SomeClass::foo, _1, 10)));

} // end code using namespaces

Explicit, readable, and doesn't affect code outside the braces
