And now to something completely different =)

sort allows providing a function name

sort SUBNAME LIST So using an ad-hoc package seems like a short way to solve this :)

  DB<138> sub sort::hours { $a->[0] <=> $b->[0] }

  DB<139> $sort = 'hours';
 => "hours"

  DB<140> *sort::this=\&{"sort::$sort"}
 => *sort::this

  DB<141> sort sort::this @records
 => (
  [5, "foo123", "world domination"],
  [7, "bar666", "have a beer"],
  [10, "xyz232", "secret project"],
)

I don't like the glob-manipulation in line 140, but it could be used to eval arbitrary complex sort routines.

Maybe others have more elegant ideas! =)

HTH!
