Reading the source code of core.clj, I've just realized that list* isn't like vec at all: the point of list* is to help the apply function, and that it doesn't even ever return lists: it always returns Cons objects (if there are two+ arguments), or a sequence (if there is one argument). The only time it returns lists is if it's given a single non-empty list argument.
Why, then, does list*'s doc say that it returns lists? Because lists are a kind of sequence? But sequences aren't a kind of list: Clojure 1.1.0-new-SNAPSHOT user=> (type (list* 1 [2 3])) clojure.lang.Cons user=> (list? (list* 1 [2 3])) ; Danger false I'll just go back to using #(apply list %). But this is very weird: if list* never returns lists (except when given a single non-empty list argument), why call it list*? And why say in the doc that it returns lists?
