Yeah, functional programming has _different_ patterns, not no
patterns. And, in some sense they also highlight shortcomings.
For example, functional languages typically do not have lists that you
can append to efficiently, so we need the "Accumulate and Reverse"
Erlang doesn't allow you to enumerate the messages a process can
receive, so we have a "Hide Message-Passing Behind Functions" pattern.
I'm sure others can pitch in with more examples.
