Is there an opposite of include? for Ruby Arrays?

Question

I\'ve got the following logic in my code:

if !@players.include?(p.name)
  ...
end

@players is an array. Is there a method so

Answer 1

if @players.exclude?(p.name)
    ...
end

ActiveSupport adds the exclude? method to Array, Hash, and String. This is not pure Ruby, but is used by a LOT of rubyists.
