I used a closure to avoid writing an in-line conditional that would be called with every iteration of the for loop. To me it made a great deal of sense, compared to:

for my $rec ( sort { if ($_ eq "PTR") { $a <=> $b} ; else { $a cmp $b 
+} } @{$dns_records{$_}} ) {
# etc
}

Update: now I see the point. The function I'm using isn't really a closure..
