At the risk of taking this too far...

We have Ronald's solution (including Steve Lane's one char improvement):

 perl -nle'$h{$r=reverse}?push@w,"$r $_":$h{$_}++}END{map print,sort@w' words

and Ilmari's solution, which has been disputed:

 perl -nle'$h{$r=reverse}?print"$_ $r":$h{$_}++' words

But this can be kludged and surprisingly is still shorter:

 sort -r words|perl -nle'$h{$r=reverse}?print"$_ $r":$h{$_}++'|sort

This also removes Ilmari's assumption that the list is sorted to start
with. ;-)

Personally I think this goes against the spirit of Perl golf, but I
bring this up, because I arrived at the Ilmari solution independently,
(but after Ilmari :-}), so I kind of wanted to defend the "home team."

And bringing two threads together (the "Wanted - Have = Need" thread's
emphasis on "Perl's not always the best solution"). I suppose there
could be two divisions of Perl golf:

  Pure Perl Golf in which you can only use Perl, no forking, no
  piping, just you, Perl and the problem.

  Perl Power Tool Golf in which you can use anything in the PPT,
  forking, piping, etc just as long as it would run on pretty much any
  platform with the PPT installed.

Kind of like "clean" and "open" (aka steroids) body building
competitions. ;-)

Hope you have a very nice day, :-)

P.S. Which reminds me of something I can't remember. Was the use of
modules legal in the Perl Golf Apocalypse? I remember forking wasn't.
