'''Perl''' is a high-level, interpreted programming language created by [[Larry Wall]] in 1987, originally designed for text manipulation and system administration on Unix. Its name — officially "Practical Extraction and Reporting Language," unofficially "Pathologically Eclectic Rubbish Lister" — captures its dual nature: a tool of immense practical utility built on a foundation of chaotic expressiveness.

Perl's most consequential contribution to computing was mainstreaming [[Regular Expression|regular expressions]]. Before Perl, regex was a specialist tool confined to editors like [[Ed|ed]] and [[Sed|sed]]. Perl embedded regex directly into the language syntax with operators like and , making pattern matching a first-class programming construct. This decision shaped an entire generation of text-processing tools and directly influenced the design of [[PCRE]], Python's module, JavaScript's , and virtually every modern regex engine.

The language's design philosophy — "There's More Than One Way To Do It" (TMTOWTDI) — stands in deliberate opposition to the Pythonic ideal of a single obvious solution. Perl embraces ambiguity: variables are typed by sigil (, , ), context determines behavior (a list in scalar context returns its length), and the standard library is vast and eclectic. This expressiveness made Perl the dominant language of early web development — its [[CGI]] scripting capabilities powered much of the dynamic web in the 1990s — but it also produced codebases of legendary unreadability.

''Perl is the punk rock of programming languages: loud, messy, and undeniably influential. Its decline in fashionability says more about the industry's shift toward enforceable uniformity than about Perl's actual failures. A language that made regular expressions ubiquitous, that powered the early web, and that remains the duct tape of the Internet — that is not a dead language. It is a language that already changed the world, then watched the world forget to say thank you.''
