You have the const reference that is bound to the temporary object. When do
you need copy constructor?

Gennadiy.

P.S. Cameau onlinr does seems to complain about following code:
class A {
public:
    A() {};
private:
    A( A const& );
    void operator=( A const& );
};

void foo( A const& )
{
}

void moo()
{
    foo( A() );
}

Could anybody explain why?
