Thread: Returning pointer to a nested class

I'm trying to compile this simple code in g++ 4.0.1:

Code:

#include <cstdlib>

template <class Data> class MyClass
{
  public:

  private:

    class Inside {};

    Inside* __func(int x);
};

template <class Data> Inside* MyClass<Data>::__func(int x) // This is line 14
{ return NULL; }

And I get :
test1.cpp:14: error: expected constructor, destructor, or type conversion before ‘*’ token

I've tried to fix it to no avail, could anyone please explain to me what am I doing wrong ?
Many thanks in advance,
stingerkiss
