+When we look at the `Monad` or `Applicative` instances of `Ior`, we can see that they actually require a `Semigroup` instance on the left side.
 This is because `Ior` will actually accumulate failures on the left side, very similar to how the [`Validated`](validated.md) data type does.
 This means we can accumulate data on the left side while also being able to short-circuit upon the first left-side-only value.
 For example, sometimes, we might want to accumulate warnings together with a valid result and only halt the computation on a "hard error"
