> a very early introduction to thinking recursively

Not everything needs to be on a so-you-have-never-programmed-before level. This series explicitly assumes "some knowledge of native-code build processes, Lisp, C, and x86 assembly language". People who know Lisp should have had an introduction to thinking recursively already.

Parsing would be a useless distraction for someone interested in writing a Scheme compiler in Scheme.
