in reply to Undefined JAPH

Great JAPH! Nice obfuscation, interesting layout, funny comments.
I do not believe anyone has used this technique before.
Sorry, I beat you to it and gave a lightning talk in 2006 at YAPC::Europe in Birmingham, titled "undef isn't", about how much more fun undef becomes once its SvREADONLY is false and you can start treating it like a variable. May I suggest tie? ;-)

    You are quite correct. In fact, your online slides helped spark the inspiration for this. Credit where credit is due. What I meant to say was "I do not believe anyone has used this technique before in a JAPH here on Perlmonks. :)
