Should I learn Perl

On my brand new Fedora 13 I notice that a lot of stuff is managed trough Perl. I'm always been curious about it, but I never watched at it, while I'm pretty good in many other languages (like C, C++, Java and Python).

What do you think about it? Is it worthy to learn it?

Perl if fun. Perl 6 is even funnier though, if you don't need die-hard software now, and like experimental/exciting compiler behaviour, try on. It feels a lot better than Perl 5, not to mention PyFOIC or something else.
