is a famous piece of Perl poetry
. It was posted to Usenet
on April 1, 1990. It is written in Perl
3 and will not parse under Perl 5. Multiple independent updates to make it parsable in Perl 5 have been published. The full text of the poem is reproduced below.
While the poem itself is signed Larry Wall
, the original message was posted with forged message headers, causing uncertainty of authorship. Sharon Rauenzahn née Hopkins has been suspected, but has denied authorship. Randal Schwartz
has claimed that Larry Wall
is in fact the author, that claim.
