    [Computation type:] Simple function application.

    [Binding strategy:] The bound function is applied to the input value.
    @'Identity' x >>= f == 'Identity' (f x)@

    [Useful for:] Monads can be derived from monad transformers applied to the
    'Identity' monad.

    [Zero and plus:] None.

    [Example type:] @'Identity' a@

    The @Identity@ monad is a monad that does not embody any computational strategy.
    It simply applies the bound function to its input without any modification.
    Computationally, there is no reason to use the @Identity@ monad
    instead of the much simpler act of simply applying functions to their arguments.
    The purpose of the @Identity@ monad is its fundamental role in the theory
    of monad transformers.
    Any monad transformer applied to the @Identity@ monad yields a non-transformer
    version of that monad.
