Again, nullable types are not "baked into" the language. They are syntax sugar for a union type. Also, Ceylon doesn't need Either, since that is just a workaround for not having union types. Seriously, union and intersection types are _really_ fundamental notions in set/type theory, and having them as basic constructs of the language makes the language _much_ more expressive. I seriously urge you to try it out. You'll love them, I guarantee it.

  "String?" is equivalent to "String|Null". Only the question mark syntax sugar is baked in.
