data Map :: (a -> Exp b) -> f a -> Exp (f b)

Type-level fmap for type-level functors.

Note: this name clashes with Map from containers. FMap is provided as a synonym to avoid this.

Example

>>> data AddMul :: Nat -> Nat -> Exp Nat
>>> type instance Eval (AddMul x y) = (x TL.+ y) TL.* (x TL.+ y)
>>> :kind! Eval (Map (AddMul 2) '[0, 1, 2, 3, 4])
Eval (Map (AddMul 2) '[0, 1, 2, 3, 4]) :: [Nat]
= '[4, 9, 16, 25, 36]
