In my experience, Perl got a lot of flak for being "write only", I don't really remember anybody complaining it wasn't "object oriented".

Every Perl code base I've seen, or inherited, has been a mess. My favourite was a bunch of utilities all written by the same person who never did anything the same way twice. Each utility was like an entry in an obfuscated 'C' contest.

I used Perl to build my first web application at LONG time ago. That project is included in the list of Perl code bases I've seen that were a mess :-)
