For instance, constructing a list by consing things onto it treats the list functionally: each cons remains unmodified after its creation. And there " The paragraph ends abruptly. I take it something is missing? (If it's meant to be a segue into Nested Collections, maybe a trailing ellipsis would be appropriate?)
