I'd prefer to see it return a boost::optional<T&>
What's the benefit?
For containers of pointers to objects, the wrapper could do an
additional dereference.
Not a good idea, it's easier to compose than decompose so return a boost::optional<T*&> and the user deref if they want to.
What problem would that avoid? It'd require the user to do an additional check. Olaf
