[Ruby] хитрый поиск по массиву

irb(main):001:0> ["linux", "org", "ru"].include? "linux" => true

Чем Array.include?(obj) не устраивает?

ri Array.include?

Returns +true+ if the given object is present in _self_
(that is, if any object +==+ _anObject_), +false+ otherwise.

        a = [ "a", "b", "c" ]
        a.include?("b")   #=> true
        a.include?("z")   #=> false

10x :)

хитро же, сцуко!
