Overview

  The perlintro(1) man page says:

      Perl is a general-purpose programming language originally developed
   for text manipulation and now used for a wide range of tasks including
   system administration, web development, network programming, GUI
   development, and more.

      The language is intended to be practical (easy to use, efficient,
   complete) rather than beautiful (tiny, elegant, minimal). Its major
   features are that it's easy to use, supports both procedural and
   object-oriented (OO) programming, has powerful built-in support for text
   processing, and has one of the world's most impressive collections of
   third-party modules.


Language features

   The overall structure of Perl derives broadly from C. Perl is a procedural
programming language, with variables, expressions, assignment statements,
brace-delimited code blocks, control structures, and subroutines.

   Perl also takes features from shell programming. Perl programs are
interpreted. All variables are marked with leading sigils. Sigils
unambiguously identify variable names, thus allowing Perl to have a rich
syntax. Importantly, sigils allow variables to be interpolated directly into
strings. Like the Unix shells, Perl has many built-in functions for common
tasks, like sorting, and for accessing system facilities.

   Perl takes associative arrays from awk and regular expressions from sed.
These simplify and facilitate all manner of parsing, text handling, and data
management tasks.

   In Perl 5, features were added that support complex data structures,
first-class functions (i.e. closures as values), and an object oriented
programming model. These include references, packages, and class-based method
dispatch. Perl 5 also saw the introduction of lexically scoped variables,
which make it easier to write robust code, and modules, which make it
practical to write and distribute libraries of Perl code.

   All versions of Perl do automatic data typing and memory management. The
interpreter knows the type and storage requirements of every data object in
the program; it allocates and frees storage for them as necessary. Legal type
conversions are done automatically at run time; illegal type conversions are
fatal errors.
