Project's home: http://www.hexstreamsoft.com/projects/enhanced-eval-when/ enhanced-eval-when provides an enhanced EVAL-WHEN macro that supports (eval-when t ...) as a shorthand for (eval-when (:compile-toplevel :load-toplevel :execute) ...), addressing concerns about verbosity. An ENHANCED-EVAL-WHEN alias is also supported, as well as an EVAL-ALWAYS macro and package nickname, for good measure. As EVAL-WHEN with all situations specified is used an overwhelming majority of the time by most users, these shorthands can really come handy. The recommended way to use enhanced-eval-when is to put (:shadowing-import-from #:enhanced-eval-when #:eval-when) in one's DEFPACKAGE. For those who would object to such shadowing, two alternatives are: (:import-from #:enhanced-eval-when #:enhanced-eval-when) ;; and (:import-from #:eval-always #:eval-always) ;; The name used for ASDF is still enhanced-eval-when. As always, it's also possible to fully qualify symbols instead, with: enhanced-eval-when:eval-when e-eval-when:eval-when eval-always:eval-always Don't (:use)! This library is in the Public Domain.
