It doesn't work as is, but the idea is sound; here's what I came up with:

int f();

template<class T> T & no_values_please(T & t);

int const & g()
{
    sizeof(no_values_please(f())); // #1
    return f(); // #2
}

It seems to work. Borland accepts #1 with a warning, but gives an error on
#2, so all is well. :-)
