OP here. Since this is a video, I'll post the abstract, etc.: by Ron Garret The lambda calculus is widely known but also widely misunderstood. It it considered by most coders to be nothing more than a theoretical curiosity and not really useful for anything by itself. In this talk, I show how to write a factorial function in pure lambda calculus, i.e. using nothing but lambdas, in a way that is actually efficient enough to compute the factorial of ten in a few seconds. Seeing how this is done can provide deep insights into functional programming, compilation, and other useful programming techniques like CPS-conversion.
