parametric-functor: A known-parametric Functor typeclass
As Oleg Grenrus argued in 2019,
Functors should be parametric, and in particular should:
Satisfy
fmap coerce=coerceHave a
∀ a b. Coercible a b ⇒ Coercible (f a) (f b)super-constraint
Until this change gets adopted in base, this package can be used for a variant of Functor
which satisfies these requirements.
