Wow, these are fantastic, especially this last one. I don't know if
this syntax (def padawan.control_the_force) has always been available
but I have long been doing that in a much more complicated way.

Please post your full list or your slides when you are finished! So
often people ask me "what's so great about Ruby" and I can't put it
into just a few sentences!
