I lived it. I'm sure there's still some Mailing List archives and IRC snippets that still endure, demonstrating the utter vicious 1-upmanship of how to do something in Perl as succinctly as possible. Why do X and Y when you can just do Z? What are you really trying to do? etc.
After that, experts would often propose multiple ways to do something when they answered questions. THEY found that intellectually playful and exciting. They still do. And for the rest of us, that was an amazing way to learn more and understand more of that tool we were using daily. Still is.
You apparently saw viciousness in this and that certainly sucks.
