java.util.Optional fields

[Vitaly Davidovich]

The main benefit of Optional, to me, is that it clearly tells the caller or
receiver that this thing may be null; the conventional way is to document
pre/post conditions, but developers are notorious for not reading docs.
Returning/taking Optional is "in your face" - the fluent API is a secondary
convenience/benefit.
