function flatmappable.createTap
import { flatmappable } from "https://deno.land/x/fun@v2.0.0/mod.ts";
const { createTap } = flatmappable;

Create a tap function for a structure with instances of Wrappable and Flatmappable. A tap function allows one to break out of the functional codeflow. It is generally not advised to use tap for code flow but to consider an escape hatch to do things like tracing or logging.
