  • I'm of aware of something exactly like that, although I've hacked stuff similar to it over, e.g., Math::Prime::TiedArray [] when playing at Project Euler []. In fact, gathering all those is_(prime|abundant|fibonacci|*) functions under a Number::Class (still trying to find a better name for it) module is something I want to do when I'll have truckloads of round tuits to spend (ah!).

  • perl -MNumber::Properties=prime \
         -MList::MoreUtils=lastval \
         -E '$x = lastval { prime } 2 .. Inf;
             say "the largest prime number is $x"'
