Comment (by mpickering):

 Perhaps it is not common but it can become increasingly cumbersome to
 manually insert lets as your program gets more complicated. Another
 example is if your program generates a small list statically in many
 different places you just want this to float outwards. Manually let
 binding it requires adding additional arguments which makes the program
 more difficult to understand.
