I'm curious as to how one would go about editing the file in place, i.e., not having to create a new outfile.

Open the file. Read the file into an array. Close the file. Open the same file for overwrite and write what you want back. 

open(IN, '<', $ifile) or die "Couldn't open file: $!\n";
my @data = <IN>;
close IN;

open(OUT, '>', $ifile) or die "Couldn't open outfile: $!\n";
foreach my $line (@data) {
    ### Do what you want
    print OUT "$line";
}

XP matters not. Look at me. Judge me by my XP, do you?
