Thank God Java EE Is Not Like Ajax
It just so happens that I'm in the camp against continuations. Looking at the negative aspects of it, I can't make the case for its inclusion into the Java spec. Continuations is simply a modern term for GOTOs and I can't understand why any sane person would want to go back to the nightmare that was GOTOs.
As for first class functions, it's inclusion will make it easy to write non object oriented code. That isn't necessarily a bad thing but then again Java was born to be an OO language.
