Stratified Design: A Lisp Tradition

How do we organize code to maximize expressivity? What makes some libraries incredibly powerful while others feel weak? One answer is stratified design, wherein we build layers of meaning on top of preexisting layers. In this talk, we will examine the ideas of Abelson and Sussman about stratified design, why it works, and how to apply it in your own code.
