Abstract
Whenever you write a program that requires a kind of data that isn’t already built into Haskell, you need to decide how to represent it in terms of the existing types. Sometimes you’ll be able to find something appropriate in one of Haskell’s library modules. Other times, you will decide to use some combination of existing types, or you’ll define a new algebraic data type.
