Swift has a "Maybe" type built in, called "Optional". I created a typealias so I could adhere to the naming convention. The unit function is also strictly unnecessary because Optional's constructor serves the same purpose. bind is also strictly unnecessary because Swift's Optional.flatmap function does the same thing.
I also created an infix operator analogous to Haskell's >>=. I can't use >>= itself because it already exists (left shift assignment) and I can't control the precedence.
