Perl

Perl is a high-level, general-purpose programming language designed by Larry Wall and initially released in 1988. It was widely used in the late ’90s and early 2000s where it was highly popular for use in CGI scripting until it was overtaken by PHP (and to a lesser extent, languages such as Python).

These days, “Perl” refers to Perl 5. There is a redesigned sister language, called Raku, which was still named Perl 6 from 2000 to 2019.
