It&#x27;s an Algol-based language. I never quite got what people &quot;got wrong&quot; with Perl code. Yes, I&#x27;ve seen bad examples, but those would&#x27;ve looked pretty much the same in C, Pascal or Python (deep nesting, bad names, overuse of regexps).<p>Back in the days one argument was using &quot;grep&quot; or &quot;map&quot; instead of explicit for-loops, but in this day of functional programming, that would seem a weird criticism.<p>Is it the type glyphs? ($%@)<p>References are a bit unnecessary, yes.
