A dict doesn't guarantee unique keys. So `dict-keys` returns a list, not a set. #lang racket (require racket/dict) (define kvs '((a 1) (a 2))) (dict? kvs) ; #t (dict-keys kvs) ; '(a a) Why does `hash-keys` also return a list? For consistency, I suppose, because every hash is a dict. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
