I saw following in IV's code. 

class Bar { /* ... */ };
class Foo {
public:
    const Bar& func() const { return bar_; }
    Bar& func() { return bar_; }
private:
    Bar bar_;
};

It seems to me that only the 2nd member function is enough. What's 
rationale for having two member functions ? (guess that I still to work
harder on my C++)

Thanks,
