Here's my latest attempt. This works on gcc 3.4.4 (cygwin), but not on

Now it works on vc7.1 too. Not como.
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().
