Build a prefix operator

Question

Suppose I have this class:

class Int{
    private:
        int x;
    public:
        Int(int i) : x(i) {}
};

Can I build a prefix + operator to write expression such x = + a b?

I tried to overload operator+ inside the class but the compiler complain that operator+ must be unary or binary and not ternary.

Is there a way to do such thing?

No you can't change the basic syntax of the expression.
