The more usual statement is that learning Lisp will change how you think about programming. Many have said that it will expand your frame of reference, and make you a better programmer in whatever other languages you end up using. I agree with them, and also that having a programming language so easily accessible inside your editor is also similarly liberating. You can decide that your editor can work more efficiently in some way, then take a few minutes to extend how your editor works, and then continue on with your original task. As languages go, I would say that Forth and Prolog also have this quality of expanding your frame of reference.
