When I try to compile the following code with G++ 2.7.0, I get an error
message:

---
template <class T> class X {
 public:
  class A {
  };
  X<T>::A GetAttr(void);
 private:
  X::A attr;
};

template <class T> void X<T>::A X<T>::GetAttr(void) {
  return attr;
};
---
test.cc:10: parse error before `<'

It seems that G++ can refer to nested classes only inside of the envelope
class, because the following works:

template <class T> class X {
 public:
  class A {
  };
  X<T>::A GetAttr(void) { return attr; };
 private:
  X::A attr;
};

However I would like to define the function out of the class declaration.

Is this a problem of C++ or of the G++ compiler?
Is there any different solution that works?
Or did I just use the wrong syntax?
