      orThunk :: this Option a -> (() -> Option a) -> Option a
        - Same as "or", but uses a thunk instead of a value

      map :: this Option a -> (a -> b) -> Option b
        - "fmap" operation on the Option Functor.
        - same as 'each'

      ap :: this Option a -> Option (a -> b) -> Option b
        - "apply" operation on the Option Apply/Applicative.
        - Equivalent to <*> in Haskell/PureScript.

      each :: this Option a -> (a -> b) -> undefined
        - similar to 'map', but doesn't return a value.
        - intended for clarity when performing side effects.

      bind :: this Option a -> (a -> Option b) -> Option b
        - "bind"/"flatMap" operation on the Option Bind/Monad.
        - Equivalent to >>= in Haskell/PureScript; flatMap in Scala.

      flatten :: {this Option (Option a))} -> () -> Option a
        - "flatten"/"join" operation on the Option Monad.

      exists :: this Option a -> (a -> Boolean) -> Boolean

      forall :: this Option a -> (a -> Boolean) -> Boolean

      filter :: this Option a -> (a -> Boolean) -> Option a

      equals :: this Option a -> Option a -> Boolean
