Introducing asyncAndThen Method!
This release introduces a new API method called asyncAndThen.
asyncAndThen is the asynchronous version of andThen.
Rather than accepting a (val: T) => Result<U, E>, asyncAndThen accepts a (val: T) => ResultAsync<U, E>.
Thank you to @jsmith and @paduc for their help in finding the bug reported in #53 and then implementing the fix / new API.
