Could you elaborate on the reason for providing that link.

LanX had already noted the new syntax ("... it was introduced with 5.20 ...") so I saw no reason to comment further in my post.

Not that you would have known, but I did check the information from a different source: https://perldoc.perl.org/5.30.0/perldata.html#Key%2fValue-Hash-Slices via https://perldoc.perl.org/5.30.0/functions/delete.html (link in second paragraph).
