The one thing I have noticed about Perl, for the times I’ve allowed it to be used in a project, is its reliability and efficient use of hardware resources. I believe FR was built using Perl? The problem with using something like Perl is its declining popularity and therefor future support - all of which makes it less appealing for use in business.
Perl is great, for the paradigm/environment it was originally designed for. There was a time when they were trying to sell it as a general purpose programming language, which it is not. It’s awk on methamphetamine. It’s garbage collection is superb. Again, makes fast and bulletproof filters. Use what is appropriate.
