I'd think you could do 
keys split

    Now you've done it. You do realize that I now feel compelled to figure out how this is done. :^)

      Actually I was being overly clever and I forgot a map keyword. Whoops =/.

      Corrected: print keys map split;

      Just add three '}', three '{', one % sign and stir. =]

        I figured there had to be a map/grep in there somewhere. Being a "Bear of Very Little Brain", map (and to a lesser extent grep) still throw me.

        You'd be thinking something like: 

           $s = 'hi, there, world, how, are you, today?';
   print join "\n", keys %{{ map {$_ => undef} (split /,\s+/, $s)}};

        And no, I didn't figure that one out by myself :-(

        Although, I rather prefer: 

           $s = 'hi, there, world, how, are you, today?';
   print (join "\n", (grep ! $t{$_}++, (split /,\s+/, $s)));

        BTW. Thanks for the puzzle ;^)
