I apologize because it's not one of the ones that you mentioned... but if you are coming from perl and want to learn something new to expand your mind, then you might want consider ruby.
From my limited experience, it seems to be the best OO-centric language for someone from a perl background. It's clear from looking at it that the folks who made it were not afraid to admit that they learned valuable lessons from perl, but at the same time did not feel limited by it. (Contrast against Python, for example, which just screams "I was based on perl", but whose proponents appear to foam at the mouth when perl is so much as mentioned (oddly).)
