There wasn't pressure to write concise code exactly, but if you posted your code somewhere the odds were good that somebody would reply with a way to do the same thing with less code, followed by someone else who managed to shave several lines/characters off of that, etc.

While almost all of the time it was all just people having fun (perl is fun and play was encouraged) and not an admonishment of the code you'd posted or an example of how it should have been written I can see how some folks might have gotten that impression. Especially if they were new to perl and were more used to languages where TIMTOWTDI wasn't thing
