The only time I use single character variable names like $k is when the scope is going to be something really small like five to ten lines. For example, 

    foreach my $k ( keys %DBhandles ) {

      $DBhandles{ $k }{ sth }->finish;
      $DBhandles{ $k }{ dbh }->disconnect; 
    }

And yes, I could minimize that to just using $_ instead of $k, but I try to never use that special variable, because it requires extra effort for the reader.

For a long time, I had a link in my .sig going to Groklaw. I heard that as of December 2024, this link is dead. Still, thanks to PJ for all your work, we owe you so much. RIP Groklaw -- 2003 to 2013.
