=head1 ACKNOWLEDGEMENTS

The first version of this document appeared on Perl Monks, where several
people had useful suggestions. Thank you, Perl Monks.

A special thanks to Damian Conway, who didn't only suggest important changes,
but also took the time to count the number of listed features and make a
Raku version to show that Perl will stay Perl.
