-The functions in the above example were intentionally simple,

-to other functions allows for flexibility when building things.
+The functions in the above example are simple. However, when passed as arguments to other functions, they can be composed in unforeseen ways to build more complex functions.
 
-For example, if we notice that we use the invocations `map(add_2, ...)` and `map(double, ...)` very often in our code, we could decide we want to create two special-purpse list processors that have the desired operation baked into them. Using function composition, we could do this as follows:
