I wonder what the "match" statement would look like on your example. This is exactly as you say though: ugly, inefficient, not-as-nice, yet works. And clearly debatable, especially as it goes against Java culture. The pattern could be used commonly, and clean-up heaps of code, and remove exception's hard-to-wrap-yr-mind-around flow jumps/etc, that I do hope for both tagged unions and match switches on them to be introduced. Some are already demo features IIRC.
