If I want to add an element to the end of an immutable list, is it better to do:
(append current-list (list new-element)) or (reverse (cons new-element (reverse current-list))) or something else? I would imagine it's the first one because that should be a single traversal and link add instead of two traversals and rebuilds, but maybe I'm wrong. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
