This is why it's lame that Swift's optionals are a language feature and not an in-language implementation.

In Haskell, optionals are Monads, which means there is a function

    join :: m (m a) -> m a

"Maybe" (Haskell's standard library Optional) is a monad, so you can unwrap/collapse them using Join.

You can also daisy-chain them together using >>=, a la

    fail1 :: Maybe a
    fail2 :: a -> Maybe b
    result = fail1 >>= fail2

If either fail1 or fail2 fails, the entire "result" function fails (i.e. returns "Nothing").
