    Fantasy Promises

    This library implements purely functional, monadic promises.

    Promise(fork)

    Promise is a constructor which takes a fork function. The fork function takes one argument:

    fork(resolve)

    The resolve callback gets called on a value.

    Promise.of(x)

    Creates a Promise that contains a successful value.

    chain(f)

    Returns a new promise that evaluates f when the current promise is successfully fulfilled. f must return a new promise.

    map(f)

    Returns a new promise that evaluates f on a value and passes it through to the resolve function.

    extract()

    Executes a promise to get a value.

    extend(f)

    Returns a new promise that evaluates f over the promise to get a value.
