[Well-Typed] The Haskell Unfolder Episode 18: computing constraints

Sometimes, for example when working with type-level lists, you have to compute with constraints. For example, you might want to say that a constraint holds for all types in a type-level list. In this episode, we will explore this special case of type-level programming in Haskell. We will also revisit type class aliases and take a closer look at exactly how and why they work.
