i've noticed in scheme, racket, , clojure expression (using clojure here) (and true '()) evaluates () , , (and '() true) evaluates true . true not empty list, list. but in gnu clisp , emacs lisp, (and t '()) evaluates nil , (and '() t) evaluates nil also, (and t '(1 2 3)) evaluates (1 2 3) , (and '(1 2 3) t) evaluates t . what going on here? in first group of languages, empty list not treated 'falsey' , instead treated 'truthy' value. in scheme , racket, #false false value though '() null, null not false; in clojure empty list not same nil, 'truthy' there well. in second group, empty list synonym nil , treated false, leading condition return nil . list elements not same nil, , treated truthy value again. the final piece of puzzle and returns last truthy value if values passed truthy.

i've read it's considered practice include $version number in of perl scripts, never understood purpose. what gain including version number in script? only modules, , pushed cpan benefit specifying $version . there's not use in script except use familiar name rather inventing new 1 if want script's version accessible. primary uses: cpan uses version of distribution, allowing index different versions of same distribution. cpan , cpanm uses check if installed module of sufficiently high level meet required minimum version of dependency. as brian d foy mentioned, can checked use foo 1.23; , people avoid in favour of specifying required versions of dependencies in distribution's meta file. allows cpan , cpanm update dependency if needed (where use using use foo 1.23; cause installation fail during testing). due lack of use of feature, it's hardly primary use.
