Perl is on the sure way to become the COBOL of the scripting world. I'm saying this as one who invested years into learning and applying Perl everywhere I could. But seriously, it's a done deal now. Move on.
Yes, there are still companies with large Perl code-bases. Large Perl code-bases need a lot of maintenance (sigh). So Perl programmers will be in some demand for a few years at the least. Hence the analogy to COBOL.
