How to remove duplicates from a list in Clojure?

How ca开发者_Python百科n I remove duplicate values from a list? For example,

(remove-duplicates ["a" "b" "c" "a"])
  => ("a" "b" "c")

user=> (distinct '(34 56 45 34 56 89 11 4 11 78 11))
(34 56 45 89 11 4 78)

If you don't care about the order, you can simply convert the list to a set:

user=> (set '("a" "b" "c" "a" "lala" "d"))
#{"a" "b" "c" "d" "lala"}

Dedupe is the faster equivalent for sorted lists since dedupe only keeps the prior element in memory.
