    Matching<S,T,A,B>
     
    Over<S,T,A,B>
    Given an Optic, a function from A to B, and a "larger" value S, produce a T by retrieving the A from the S, applying the function, and updating the S with the B resulting from the function.
    Pre<P extends Profunctor<?, ?, ? extends P>, S, T, A, B>
    Turn an Optic with a unary mapping that can be used for viewing some number of values into an Optic that views the first value, if it exists.
    Re<S,T,A,B>
    Turn an Optic with a unary mapping that can be used for setting (e.g.
    Set<S,T,A,B>
    Given an Optic, a "smaller" value B, and a "larger" value S, produce a T by lifting the Optic into the Identity functor.
    Under<S,T,A,B>
    The inverse of Over: given an Iso, a function from T to S, and a "smaller" value B, return a "smaller" value A by traversing around the type ring (B -> T -> S -> A).
    View<S,T,A,B>
    Given an Optic and a "larger" value S, retrieve a "smaller" value A by lifting the Optic into the Const functor.
