📌 Ranges and Enum
Ranges can be constructed from any instance of Haskell's Enum typeclass,
including custom types that derive from Enum. For example, the custom Day
type below:
data Day = Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday deriving (Show, Enum)
[Monday .. Friday]
-- returns
[Monday,Tuesday,Wednesday,Thursday,Friday]
