Lambda the Ultimate

In an effort to understand how ActorScript is to program with, and because I think Stepanov's "Elements of Programming" represents the best 'core' for any generic programming library, I want to try and translate the Elements into ActorScript. As there is no environment for actually testing code I thought I would post it here for comments from those who can tell if its correct or not. The idea is each top-level post should be a block of Elements code in ActorScript for comments. I will revise the top-level code according to the corrections and suggestions in the comments. I don't plan on using Unicode, but I will try and get the ASCII representations correct too.
