This was proposed previously:

class Object
  def in? enum
    enum.include? self
  end
end

IIRC the resolution was that an object being a part of a collection is
not a property of the object but rather a property of the collection
=E2=80=93 hence the existence of Enumerable#include? and the inexistence of
Object#in?

have been telling people at work that I have a special variant
of Tourette=E2=80=99s that is only triggered by reading or writing Java
