* A typical use case for `contramap` would be like, given some `User` type, to construct an `Ord<User>`.
*
* We can do so with a function from `User -> X` where `X` is some value that we know how to compare
* for ordering (meaning we have an `Ord<X>`)
*
* For example, given the following `User` type, there are lots of possible choices for `X`,
* but let's say we want to sort a list of users by `lastName`.
*
* If we have a way of comparing `lastName`s for ordering (`ordLastName: Ord<string>`) and we know how to go from `User -> string`,
* using `contramap` we can do this
*
* @example
* import { pipe } from 'fp-ts/function'
* import { contramap, Ord } from 'fp-ts/Ord'
* import * as RA from 'fp-ts/ReadonlyArray'
* import * as S from 'fp-ts/string'
*

* readonly firstName: string
* readonly lastName: string
* }
*
* const ordLastName: Ord<string> = S.Ord
*
* const ordByLastName: Ord<User> = pipe(
* ordLastName,
* contramap((user) => user.lastName)
* )
*
* assert.deepStrictEqual(

* { firstName: 'a', lastName: 'd' },
