Subject: Re: [ANN] Dwemthy's Array -- the Ruby mini_adventure

Oh btw, if you keep at it the DwemthysArray gets a little nasty
sending messages to Nil and nil does not seem to appreciate the extra
attention. So a minor change like below seems to help.

Thanks as always for the enjoyable read, yours is one of the more
interesting ways to introduce people to Ruby.
