I also have never seen a poem wrote in Java.

I'm not sure whether the possibility of writing "poems" in Perl really means anything.

Perl can also be an OO language and is much faster depending on the job you are doing

Well, if language A is faster than language B depending on the job you are doing, doesn't that mean that language B is also faster than language A depending on the job you are doing? Assuming the change is zero that for a particular job, both languages are as fast, it means that for some, but not all, jobs, language A is faster. Hence, there are jobs for which language A isn't faster, and therefore, language B is faster.
