perl(1) is a scripting language for Unix systems. It borrowed and built upon the syntax of Unix tools like ed and awk, and in turn inspired the PCRE (Perl Compatible Regular Expressions) and PCRE2 libraries.
This article refers to Perl 5, not Raku.

perl(1) is better known for its powerful yet obfuscated syntax, especially in the spirit of Bash one-liners. As an example (credit to Randal L. Schwartz):
perl <<<'print join " ", reverse split " ", "hacker, Perl another Just"'
Or more humorously (credit to Raymond Chen):
perl <<<'$_="krJhruaesrltre c a cnP,ohet";$_.=$1,print$2while s/(..)(.)//;'
