Perl ABCMaintainable Perl 7 plan
As of 2021, Perl 7 with high maintainability is planned. Perl7 is a new version of Perl that improves the maintainability of Perl, reduces beginner mistakes, and maintains high backward compatibility with the current version of Perl5.
With the following description, it is planned to be able to use the functions of Perl7. The release date is undecided.
use v7;
In the description of "use v7 ", "use strict;" which makes Perl grammar strict and "use warnings;" which outputs warnings are enabled, and you can write Perl with high maintainability in one line description.
You can use functions that were available as Perl 5 features, such as the say function.

What happened to Perl 7's announcement?
There was Perl 7 announcement on Perl.com in June 2020, but it was announced. The content is now updated.
What happened to Perl6?
Perl6, which was once developed as a successor to Perl5, has been renamed to Raku. As of 2021, some sites mention Perl 6 as it is without updating the information, but the correct information is that Perl 6 has been renamed to Raku.
Relationship between Perl 7, Perl 6, and Perl 5
