Making Two Passes

• The next block in the program is the same loop with a different body:

     326  foreach $filesz (sort { $b <=> $a } keys %names_by_size)
     327  {
        ...
     338  }

     354  foreach $filesz (sort { $b <=> $a } keys %names_by_size)
     355  {
        ...
     463  }

• Usually, I like to advise that such loops be merged, if possible.

• In this case, I wonder if that's good advice

• That second loop is already way too big

• (Note: It would be 1/3 smaller without the comments.)
