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 Perl 6 version to show that Perl will stay Perl.
