I'm not a common lisp user, but I want to be. I want to learn common lisp, and I have a fair understanding of types. I think types can benefit the user in understanding more, as well as the inbuilt "intelligence" - (aka: How am I meant to know ahead of time that I can't add these two objects together? Having the editor tell me as I'm writing is a great step)

I have "mine" their text editor, now I just need some tutorials and sample projects to go with it.
