         Practical Extraction and Report Language (PERL)

      [Practical Extraction and Report Language, a.k.a. Pathologically Eclectic
      Rubbish Lister] An interpreted language developed by Larry Wall, author of
      patch(1) and rn(1)). Superficially resembles awk, but is much hairier,
      including many facilities reminiscent of sed(1) and shells and a
      comprehensive Unix system-call interface. Unix sysadmins, who are almost
      always incorrigible hackers, generally consider it one of the languages of
      choice, and it is by far the most widely used tool for making ?live? web
      pages via CGI. Perl has been described, in a parody of a famous remark
      about lex(1), as the Swiss-Army chainsaw of Unix programming. Though Perl
      is very useful, it would be a stretch to describe it as pretty or elegant
      ; people who like clean, spare design generally prefer Python. See also
      Camel Book, TMTOWTDI.

From The Free On-line Dictionary of Computing (30 December 2018) :

      A high-level programming language, started
     by Larry Wall in 1987 and developed as an open source
     project.  It has an eclectic heritage, deriving from the
     ubiquitous C programming language and to a lesser extent
     from sed, awk, various Unix shell languages, Lisp,
     and at least a dozen other tools and languages.  Originally
     developed for Unix, it is now available for many
     Perl's elaborate support for regular expression matching and
     substitution has made it the language of choice for tasks
     involving string manipulation, whether for text or binary
     data.  It is particularly popular for writing CGI scripts.
     The language's highly flexible syntax and concise regular
     expression operators, make densely written Perl code
     indecipherable to the uninitiated.  The syntax is, however,
     really quite simple and powerful and, once the basics have
     been mastered, a joy to write.
     Perl's only primitive data type is the "scalar", which can
     hold a number, a string, the undefined value, or a typed
     reference.  Perl's aggregate data types are arrays, which
     are ordered lists of scalars indexed by natural numbers,
     and hashes (or "{associative arrays") which are unordered
     lists of scalars indexed by strings.  A reference can point to
     a scalar, array, hash, function, or filehandle.  Objects
     are implemented as references "{blessed" with a class name.
     Strings in Perl are eight-bit clean, including nulls, and
     so can contain binary data.
     Unlike C but like most Lisp dialects, Perl internally and
     dynamically handles all memory allocation, garbage
     collection, and type coercion.
     Perl supports closures, recursive functions, symbols
     with either lexical scope or dynamic scope, nested data
     structures of arbitrary content and complexity (as lists or
     hashes of references), and packages (which can serve as
     classes, optionally inheriting methods from one or more
     other classes).  There is ongoing work on threads,
     Unicode, exceptions, and backtracking.  Perl program
     files can contain embedded documentation in POD (Plain Old
     Documentation), a simple markup language.
     The normal Perl distribution contains documentation for the
     language, as well as over a hundred modules (program
     libraries).  Hundreds more are available from The
     Comprehensive Perl Archive Network.  Modules are themselves
     generally written in Perl, but can be implemented as
     interfaces to code in other languages, typically compiled C.
     The free availability of modules for almost any conceivable
     task, as well as the fact that Perl offers direct access to
     almost all system calls and places no arbitrary limits on
     data structure size or complexity, has led some to describe
     Perl, in a parody of a famous remark about lex, as the
     "Swiss Army chainsaw" of programming.
     The use of Perl has grown significantly since its adoption as
     the language of choice of many web developers.
     CGI interfaces and libraries for Perl exist for several
     platforms and Perl's speed and flexibility make it well
     suited for form processing and on-the-fly web page creation.
     Perl programs are generally stored as text source files,
     which are compiled into virtual machine code at run time;
     this, in combination with its rich variety of data types and
     its common use as a glue language, makes Perl somewhat hard to
     classify as either a "{scripting language" or an
     "{applications language" -- see Ousterhout's dichotomy.
     Perl programs are usually called "Perl scripts", if only for
     historical reasons.
     Version 5 was a major rewrite and enhancement of version 4,
     released sometime before November 1993.  It added real data
     structures by way of "references", un-adorned subroutine
     calls, and method inheritance.
     The spelling "Perl" is preferred over the older "PERL" (even
     though some explain the language's name as originating in the
     acronym for "Practical Extraction and Report Language").  The
     program that interprets/compiles Perl code is called
     "perl", typically "/usr/local/bin/perl" or "/usr/bin/perl".
