I am a new person at my job, and I started going through a lot of the Perl scripts. The previous employee is doing a lot of this:

$hotfix=join "", "$app", "_", "$mod", "_", "$bld", "_", "$hf", ".zip";
$fullpath=join "", "$Upload_Loc", "/", "$filename";

While I would probably do something like this

$hotfix = "${app}_${mod}_${bld}_${hf}.zip";
$fullpath = "$Upload_Loc/$filename";

Or maybe

$hotfix = join("_", $app, $mod, $bld, $hf) . ".zip";
$fullpath = $Upload_Loc . "/" . $filename;

Is there a reason why his way may be better than my way?
