As I read this, Greenspun's tenth rule of programming humorously came to mind: "Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp."

Generalized by replacing "C or Fortran" with a language where the user wants more power over it's syntax and semantics, to witness the author pull it off in just 44 lines of JavaScript was a joy.
