def inspect(max_elements = 10)
  if self.length <= max_elements
    old_inspect()
  else
    '#<' + self.class.to_s + ':' + self.object_id.to_s + '>'
  end
end

#old_inspect ⇒ Object

Redefine inspect to only print for small numbers of items. Prevents exceptions taking forever to be raised with large objects. See blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/105145
