"Using" declaration with scope only on current class?

Question

Is there a possibility to have a using directive whose scope is limited to a single class?

Note, that what I want to "use" is not contained in the parent of the current class.

For simplicity, assume the following exmple:

#include<vector>

class foo
{
using std::vector; //Error, a class-qualified name is required
}

Another interesting thing to know is, if the using directives are included, if a header is included:

MyClassFoo.h:
#include<vector>

using std::vector; //OK
class foo
{

}

And in

NewHeader.h
#include "MyClassFoo.h"
...

how can I prevent "using std::vector" to be visible here?

Answer 1

Since you tagged c++11:

#include<vector>

class foo
{
  template<typename T>
  using vector = std::vector<T>;
};
