Thanks. I'll keep my eye on Neil's Perl Quirks locked down document and update this node when it's finally made public. Meanwhile, please feel free to add your suggestions to my initial list.

Note to pollsters: please hold off creating a poll on this topic until Neil's document is made public.

Update Oct 2022: The Perl Quirks document appears to be stalled. p5p mailing list refs:

• June 25 2021 by Neil Bowers
• July 29 2021 by Joel Roth
• July 10 2021 by Neil Bowers
• August 4 2021 by Neil Bowers

Looks like it won't make poll ideas quest 2022. Perhaps resurrect in 2023.

Update Nov 2023: Given this document still appears to be stalled, it seems safe to assume that it will never be made public.
