in reply to Reverse Engineering Perl Tool?

You might want to use Deparse to show you the reduced syntax, this will produce slightly prettier output, which might help you a little.

# bad perl print $foo; s/dog/cat/gm; m%foo%; FOO: for ($foo) { /dog/ && do {last FOO}; /cat/ && do {$dog = 'rabbit' +};} exit(0) or die "wooot?";

When run through Deparse:

bash-2.03$ perl -MO=Deparse badperl.pl badperl.pl syntax OK print $foo; s/dog/cat/gm; /foo/; FOO: foreach $_ ($foo) { if (/dog/) { last FOO; } if (/cat/) { $dog = 'rabbit'; } } die 'wooot?' unless exit 0;

As you can see, some bits get clearer, while others get a little more murky, but it's a useful tool.
