Hmm.. this argument seems to be lacking a through knowledge of PHP.
Though not modules, using PHP includes with self contained classes emulates this functionality quite easily. and I'm assuming your strict argument and global are the same. Kinda moot there but variables are not all "global" in PHP.
Quite frankly PHP is much easier for many cgi functions than perl, that being said Perl is more powerful and obviuosly has the advantage of being much more mature a language. I just find your arguments weak.
