I came across this a while back whilst googling about for something or other related to that fun language at which I suck (LISP), and I’d almost forgotten about it until a discussion on the sickness of Python this evening reminded me. And so now I present Casting SPELs in LISP. Fun for all the family.
[ Edit! And while I’m here I may as well MLP to: Buster Wilde because its well funny. Ahh go on admit it. ]
