 About the error message in this posted code:

> class T {
>   T();
>   ~T();
> }
> 
> class X {
>   X();
>   ~X();
>   f(T& t);
> }
> 
> int main() {
>   X x;
>   x.f(T());  // Compiler complained on this line
> }

The 'temporary' (it is an UNNAMED) T()-object is NOT const!
Consider:
	class T {
	public:
		T();
		~T();
		void nonConstFct() {}
	};

	int main() {
		T().nonConstFct();  // Allowed!!!
	}

And so the compiler should have no problem with this code!
I compiled it without any problem!

Bye.
