;;;; CMPENV-PROCLAIM -- Proclamations for the compiler
;;;;
;;;; One implementation of PROCLAIM that uses symbol properties to
;;;; store the proclamations. This has the disadvantage that
;;;; proclamations can not be easily cleaned up.
;;;;
;;;; The following code is to be coordinated with that in sysfun.lsp
;;;; and proclamations.lsp
