Closing Scripts - What's Happening?

The analyzer is looking at the forms that have been read by the reader. It's just, it basically says, oh, okay, I need to like analyze this form, if you will. And one of the things that it'll do is it'll look at the very first thing in that list and it'll say, is that symbol actually a macro? Does it refer to a macro? If so, it calls them, it calls the macro right there. So all the warnings that appear that you ever see out of closure scripts are from the analyzer.
