3 Optimizing Lisp Programs

3.5 Development mode optimizations

In development mode, which is the default mode, the Compiler performs only the following optimizations on the compiled code:

All other optimizations described in this chapter are ignored. In particular, the Compiler does not perform the following optimizations:

(+ 1 2)
(* 2.0 pi)
(aref \#(a b c) 1)
(car '(a b))

When you want to use these optimizations, you must select the production mode of the Compiler.
