Higher kinded types for typescript and a few utility monads.

import { monad } from "./monad.js";
import { id, pipe } from "../core/utils.js";
const is_monadTrans = Symbol("is_monadTrans");
/** Creates a monad that can transform another monad from an `IMonadTransBase`. */
export function monadTrans(base) {
    if (is_monadTrans in base)
        return base;
    return pipe(base, base => ({
        ...monad(base),
        ...base
    }), base => {
        const flatten = (fa) => base.bind(base.lift(fa), id);
        return {
            [is_monadTrans]: true,
            flatten,
            ...base,
        };
    });
