This is a Christmas-themed programming puzzle for my old flatmate Samuel. It starts off by parsing a strange syntax tree, then requiring you to evaluate it with some binding limbs. I recommend it to people who are interested in learning and thinking about parsers and interpreters. It is not that hard, but a bit tricky.
