Using higher-order functions in the context of IO operations is possible, but requires some new ingredients. We discuss the function sequence that can turn a list of IO actions into a single action returning a list, and how sequence can be used in order to define a variant of map that is suitable if the function we want to map with results in an IO action. We also discuss a variant of filter for filtering with an IO-based test.
