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. As EVAL-WHEN with all situations specified is used an overwhelming majority of the time by most users, this shorthand can really come handy!
