Closing Script - What Is It All About?

Closures always had this feature where you can pass various options to it. And closure script on the other hand has always been kind of tedious to run as a compiler. Well, CLJS main basically says, let's let's add all the same kind of options that you have for closure into closure script. You can now just fire up a REPL or compile something. It acts more like a compilation now. There's another cool feature coming up that we haven't mentioned: master is a feature to warn you about using private vars.
