Good point. But you can't reach the simplifying insight by any other road than your own initial stupidity. It's the way you learn Lisp. At least Lisp breaks you with grace -- quick and painful. Most other languages spare you the pain of insight.

And I'm consistently surprised by how easy it is to root out my stupidities once I've recognized them, thanks to the repl, a functional style and a small code base. Lisp teaches you to face your fears.
