To my knowladge the Java library does not although it is fully capable of supporting this. I guess this is just an example of poor implementation. It could have been easily implemented like this Optional<X> x = ...; switch (status(x)) { case SOME: return x.get() * 10; case NONE: .... send error ... } Again I really like the matching functionality but as it stands, since it's not included, it's not worth much without it in my opinion. With match, that cleans up a LOT of code and if the compiler can guarantee no speed or memory hits for doing this it becomes very valuable very quick. It's one of the reasons I wanted to learn Rust.
