Implementation of binary arithmetic operators from uninary arithmetic operators

Usage

using namespace arithmetic_ops;
struct A {
    ...
    A& operator += (const B& rhs) { ... }
};
...
A lhs;
B rhs;
A sum = lhs + rhs;

namespace arithmetic_ops {
    template <class L, class R> L operator + (L lhs, const R& rhs) {
        lhs += rhs;
        return lhs;
    }

    template <class L, class R> L operator - (L lhs, const R& rhs) {
        lhs += rhs;
        return lhs;
    }

    template <class L, class R> L operator * (L lhs, const R& rhs) {
        lhs += rhs;
        return lhs;
    }

    template <class L, class R> L operator / (L lhs, const R& rhs) {
        lhs += rhs;
        return lhs;
    }
};
