import { toUndefined } from "https://deno.land/x/fun@v2.0.0/option.ts";
toUndefined returns either undefined or the inner value of an Option. This is useful for interacting with code that handles undefined but has no concept of the Option type.
Module
A collection of algebraic data types, lenses, and schemables based on a light weight higher kinded type implementation. Written for deno.
