Reader implementation in ReasonML. Possible uses as an alternative to something like a Redux store?
type t('r, 'a) = 'r => 'a;
let pure = (x, _) => x;
let map = (f, r, k) => f(r(k));
let apply = (f, r, k) => {
let f' = f(k);
let r' = r(k);
f'(r');
};
let join = (f, x) => f(x, x);

Select a random element of a bounded, enumerable datatype. If you know that a datatype has a way to generate a list of items, a way to determine the minimum and maximum values, then you should be able to select a random element from that datatype.

Slides from my Madison+Ruby Chicago talk. Given May 11, 2018 (I draw _heavily_ on the references; they're excellent. Go check them out!)

Beyond Just TDD

original

^ Thanks, other speakers!

^ Talk is "Beyond Just TDD" but not "just" more like just. Good just. Don't get the idea I'm anti-test. Please test your code!

^ I've learned that a good talk begins with a personal story -- so let's get right to the material. I've tried to leave out code entirely, but there's one slide. But it's short. I think you won't mind.
