import { all } from "https://deno.land/x/eitherway@0.10.0/lib/async/tasks.ts";
Use this to collect all Ok<T> values from an Array<Task<T,E>> or
Iterable<Task<T,E>> into an Task<T[],E>.
Upon encountring the first Err<E> value, this value is returned.
This function also works on variadic tuples and preserves the individual types of the tuple members.

import { Task, Tasks } from "./mod.ts";
import { Result } from "../core/result.ts";
const str = "thing" as string | TypeError;

const bool = true as boolean | ReferenceError;
const tuple = [
Task.of(Result(str)),
Task.of(Result(num)),
Task.of(Result(bool)),
] as const;
const res: Result<
readonly [string, number, boolean],
TypeError | RangeError | ReferenceError
> = await Tasks.all(tuple);
