+/**
+ * The `Applicative` type class extends the `Apply` type class with a `of` function, which can be used to create values
+ * of type `f a` from values of type `a`.
+ *
+ * Where `Apply` provides the ability to lift functions of two or more arguments to functions whose arguments are
+ * wrapped using `f`, and `Functor` provides the ability to lift functions of one argument, `pure` can be seen as the
+ * function which lifts functions of _zero_ arguments. That is, `Applicative` functors support a lifting operation for
+ * any number of function arguments.
+ *
+ * Instances must satisfy the following laws in addition to the `Apply` laws:
+ *
+ * 1. Identity: `A.ap(A.of(a => a), fa) <-> fa`
+ * 2. Homomorphism: `A.ap(A.of(ab), A.of(a)) <-> A.of(ab(a))`
+ * 3. Interchange: `A.ap(fab, A.of(a)) <-> A.ap(A.of(ab => ab(a)), fab)`
+ *
+ * Note. `Functor`'s `map` can be derived: `A.map(x, f) = A.ap(A.of(f), x)`
+ *
+ * @since 2.0.0
