Consider

my $val ||= "undefined"

Which is equivalent to: 

if (!$val) {
    $val = "undefined";
}

Blocks of code like that tend to clutter up your code.

Also consider: 

$val = ($val) ? "defined" : "undefined";

[download]

Which is equivalent to: 

if ($val) {
    $val = "defined";
}
else {
    $val = "undefined";
}

Also, remember perl evaluates expressions for truth.
