I just remembered what I meant when I wrote that: "I hadn't expected a
simple implementation of the ray tracer written in Lisp or Scheme to be
able to compete in terms of performance...".

In other words, I was expecting fast Lisp/Scheme implementations of the ray
tracer to be obfuscated compared to the other languages but that doesn't
seem to be the case.
