A monkeypatch for Object in Ruby which is basically the opposite of Array#include?. You can take an any object and call "in?" on it with an array as the parameter, and it will check whether the subject object is in that array.

def in?(array)
# Returns true if the Object that this is called on is included in
# the array passed in, otherwise returns false
array.include? self
end
