Package: COMPILER
If the value of this variable is true, CLtL-1 compile-time-too behavior will be used when compiling a file. That means that top-level forms calling the functions listed below need not be wrapped in an appropriate eval-when form in order for them to have effect while a file is being compiled. If the value is the symbol warn (which is the initial value), a warning will be printed whenever a form is encountered where CLtL-1 compile-time-too behavior is used. (Note: it is likely that complex files will generate many warnings.) If the value is nil, ANSI compile-time-too behavior is used. We recommend that you modify all files to conform to ANSI behavior as soon as possible.
By compile-time-too behavior, we refer to the effect of certain top-level forms in a file being compiled. In CLtL-1, top-level forms which were calling the functions listed below were treated as if they were wrapped in an
(eval-when (compile))
form. That behavior has been changed in the new standard and you must wrap such forms in appropriate eval-when forms if they are to have effect while a file is being compiled. The affected functions are:
proclaim
make-package
shadow
shadowing-import
import
export
unexport
use-package
unuse-package
require
