Perl: how these two variables are equal numerically?

[Hoffmann]

Could some one explain how, in the example below, $name and $goodguy are 
equal numerically?

$name    = 'Markkkk';
$goodguy = 'Tony';

if ($name == $goodguy) {
       print "Hello, Sir.\n";
} else {
       print "Begone, evil peon!\n";
}

Thanks,
Hoffmann
