import { type fn_either } from "https://deno.land/x/fun@v2.0.0/mod.ts";
const { KindRightFnEither } = fn_either;
Specifies FnEither as a Higher Kinded Type, with covariant parameter A corresponding to the 0th index of any Substitutions and a contravariant parameter D corresponding to the 0th index of any Substititions. KindRightFnEither curries the Left parameter of the output Either. This is useful when one needs to Fix the Left output with a Combinable or some other collection algebraic structure.
