#convenience#library#public-domain#trivial

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.
