Finally, it is this very simplicity of syntax and semantics that is responsible for the burden and freedom borne by all Lisp programmers. No Lisp program of any size beyond a few lines can be written without being saturated with discretionary functions. Invent and fit; have fits and reinvent! We toast the Lisp programmer who pens his thoughts within nests of parentheses.

最後,正是這種語法和語意的極端簡單性,產生出來了所有 Lisp 程序員的負擔和自由。任何規模的 Lisp 程序, 除了那種寥寥幾行的程序外,都飽含著考慮周到的各種功能。 發明並調整,調整恰當後再去發明!讓我們舉杯,祝福那些將他們的思想鑲嵌在重重括號之間的 Lisp 程序員。
