Traverse is specially usefull when gathering multiple operation started in parallel in order to revert a List<Deferred<A>> into a Deferred<List<A>> meaning gathering all the results non blocking. If you notice the shapes are the same as you are trying to do. That is why learning the type classes is in my opinion more important than learning specific data types APIs.
