That&#x27;s interesting, I had no idea. There&#x27;s probably a way more detailed Rosetta Code style project that could cover all these nuances, but for a single page demo, there&#x27;s only so much detail I can get into before it would be more confusing than helpful.<p>If you&#x27;d like to flesh out the perl section a bit though, maybe include the differences between 5 and 6, I&#x27;d be happy to merge a pull request.
