Consider code like this:

  def do_sth_on(this)
    if this.kind_of?(Enumerable)
      this.map {|item| do_sth_on(item) }
    else
      # whatever
    end
  end

This is a method that either works on a collection or on single item. As
soon as a you make Object behave like Enumerable, this breaks and leads
to recursion.
Always very dangerous to modify core classes and in this case it seems
suicidal :)
