Oops, my fault. But the following works, at least on the 3.3.1 where I 
tested it 2 minutes ago :)

template<class T, class U> struct operator_plus_result
{
    static T t();
    static U u();
    typedef __typeof__( t() + u() ) type;
};

template<class T, class U>
typename operator_plus_result<T,U>::type
sum(const T& t, const U& u)
{
    return t + u;
}

int main()
{
    sum(5, 3.14);
}

Regards, Daniel
