Issue: DEFINE-OPTIMIZER

[Jim McDonald <jlm@lucid.com>]

On reflection, most of my arguments probably evaporate for optimizers
of routines not provided by vendors.  I was misled a bit by the use of
STRING-APPEND in the example, which happens to be in Lucid's SYSTEM
package, and which I mistakenly thought was standard Common Lisp.
