In this episode we’ll discuss the the four different ways GHC offers for deriving class instance definitions: the classic “stock” deriving, generalised “newtype” deriving, as well as the “anyclass” and “via” strategies. For each of these, we’ll explain the underlying ideas, use cases, and limitations.
