Personally, I agree with your choices on rebinding and the "pointer
style" interface. The safe_bool idiom is too handy to pass up - it
allows you to do nice things like declaring variables in an if
expression, and the main reason to overload operator->() is because you
can't overload operator.(). Sure it's sugar, but it's tasty and makes
life easier.

That's the best description and rationalization of the semantics of
optional<T&> I've heard yet.
