Example
print "Hello, World!\n";
Execute this file by running:
perl hello.pl
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/(..)(.)//;'
