(Generic a, GSemigroup' (Rep a)) => GSemigroup (Default a) # | Semigroups often have many sensible implementations of `<>` / `gsappend`, and therefore no sensible default. Indeed, there is no `GSemigroup'` instance for representations of sum types. In other cases, one may wish to use the existing wrapper newtypes in `base`, such as the following (using `First`):
    newtype FirstSemigroup = FirstSemigroup Bool
      deriving stock (Eq, Show)
      deriving (GSemigroup) via (First Bool)
