Is there an opposite of include? for Ruby Arrays?
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.

Here you go:
unless @players.include?(p.name)
...
end
You might have a look at the Ruby Style Guide for more info on similar techniques.
How about the following:
unless @players.include?(p.name)
....
end
