How to generate a non-const method from a const method?

Question

While striving for const-correctness, I often find myself writing code such as this

class Bar;

class Foo {
public:
  const Bar* bar() const { /* code that gets

You can do something like this:

class Bar;

class Foo {
public:
  const Bar* bar() const { return getBar(); }

  Bar* bar() {
   return getBar();
  }

  private:
    Bar* getBar() const {/* Actual code */ return NULL;}
};
