using class (like with namespace)

[ne555]

I've got something like

class foo{
public:
  typedef float value_type;
  typedef std::valarray<value_type> vector;
private:
  vector w;
};

In order to code its methods I need to do

foo::value_type foo::some_method(const vector &v ){
  value_type result; //no need of qualification 

So, ¿how could avoid having to type foo:: before parameters and return value?

I could

//foo.cpp
typedef foo::value_type value_type;
typedef foo::vector vector;

, ¿but what about private typedef/inner classes?

Just notice that the qualification is not needed in the parameters list (at least with gcc 4.6.1)
Maybe I don't care anymore, xP
