One way is mentioned in the new C++ ARM. It is as follows:

//
// Class tracer will trace entering and leaving a function. Just
// Declare a Tracer variable at the beggining of the function.
//
// test() {
//    Tracer trace("test");
//    ...
// }

class Tracer {
	const char *mess;
public:
	Tracer(const char *m) { mess=m; cout << "Entering("<<m<<")" << endl; }
	~Tracer() { cout << "Exiting("<<mess<<")" << endl; }
};

This class traces entry and exit of the scope where it is declared.
It is a little easier then what you suggested, but still not generated
automatically.
