Btw, the error on como is down to one, name the line

      char t1[!IS_RVALUE(f1)];

(remember to compile with --a or --A)

To unconfuse the compiler, one might try to add another utility:

template< class T >
struct ref_probe
{
   operator T&();
};

template<class T >
ref_probe<T> make_probe( T& );

now the conversions from probe<T> should only happen for const T& and T().
