function optics.compose
import { optics } from "https://deno.land/x/fun@v2.0.0-alpha.6/mod.ts";
const { compose } = optics;

Compose two Optics by:

  1. Finding the alignment of them, which is Max<first, second> where Fold > Affine > Get
  2. Cast both optics to the alignment tag, one cast will always be a noop.
  3. Construct a new optic by chaining the view functions first to second and composing the modify functions second to first.
