After recommending the Schwartzian Transform to someone recently (and directing them to http://www.5sigma.com/perl/schwtr.html as a reference) I meditated that someone has probably written a module to encapsulate the Schwartzian Transform. I looked but couldn't see one.

I was thinking of something like:

  $file_size_sort = new Sort::Schwartzian
       left => '-s $a', op=>'<=>', right =>'-s $b';

[download]
... later ...

  @sorted = $file_size_sort->(@files);

[download]
or 
  $sort_by_score = new Sort::Schwartzian
       left => '$b->score', op=>'<=>', right =>'$a->score';

[download]
etc.

If such a thing doesn't exist I'm suggesting someone write one. Volunteers?
