This section covers structural properties of intersection types and documents some decisions on how
to represent mixtures of intersections and unions.
### Single-element unions
### Single-element intersections
If we have a union of a single element, we can simplify to that element. Similarly, we show an
intersection with a single negative contribution as just the negation of that element.

If we intersect a type `X` with the negation of a disjoint type `Y`, we can remove the negative

If we intersect a type `X` with the negation `~Y` of a disjoint type `Y`, we can remove the negative
