Description
Simply (:shadowing-import-from #:enhanced-eval-when #: from your defpackage. Don't eval-when)(:use)!
enhanced-eval-when
enhanced-eval-when provides an enhanced eval-when macro that supports
( as a shorthand for
eval-when t ...)
(,
eval-when (:compile-toplevel :load-toplevel :execute) ...)
addressing concerns about verbosity.
As eval-when with all situations specified is used an overwhelming majority
of the time by most users, this shorthand can really come handy!
