values, and where those values describe properties, for example the length of a list, the type of a function can begin to describe its own properties. Take for example the concatenation 1 Typically, and perhaps the sum of the lengths of the two input lists. We can therefore give the following type to the app function, which concatenates vectors: app : Vect n a -> Vect m a -> Vect (n + m) a This tutorial introduces compiled language which aims to generate efficient executable code. It also has a lightweight foreign function interface which allows easy interaction with external C libraries. 1.1.1 Intended Audience This
