I agree on the ADT part, but I think it is only one of the three major complaints brought up.
The other ones are: - Is no collection/doesn't implement Iterable/Stream/... - Is no monad/lacks map/filter/flatMap It is certainly a bit confusing that he added ifPresent almost at the same time (which is more or less equivalent to a foreach). Not sure whether it helps people learning the language or the new APIs when equivalent things are named differently throughout implementations/interfaces... The positive thing is that I was already concerned that we would have two different Option/Optional types in the future and confusion which one to use, but that won't happen as far as I see. :-) -- You received this message because you are subscribed to the Google Groups "Java Posse" group.
