Don't you hate it when you have

class Foobar {
public:
    Something& getSomething(int index) {
        // big, non-trivial chunk of code...
        return something;
    }

    const Something& getSomething(int index) const {
        // big, non-trivial chunk of code...
        return something;
    }
}

We can't implement either of this methods with the other one, because you can't call the non-const version from the const version (compiler error). A cast will be required to call the const version from the non-const one.

Is there a real elegant solution to this, if not, what is the closest to one?
