Ruby removing duplicates in enumerable lists

Question

Is there a good way in ruby to remove duplicates in enumerable lists (i.e. reject, etc.)

Answer 1

For array you can use uniq() method

a = [ "a", "a", "b", "b", "c" ]
a.uniq   #=> ["a", "b", "c"]

so if you just

(1..10).to_a.uniq

or

%w{ant bat cat ant}.to_a.uniq

because anyway almost every methods you do implement will return as an Array class.
