It's grand child, Raku, also seems to be an impressive language actually. Hated by Perlers and non-Perlers alike, it actually would be a great environment to build powerful programs in:

Yeah, Perl 6 created a lot of confusion especially inside the Perl 5 community. But, in the end, they figured it all out: Perl 5 lives on and Perl 6 got out of its way by renaming itself to Raku. And, for the record: Raku itself is a gem of a language, I believe. A pretty solid OO system, optional typing, powerful language constructs, stellar Unicode support and somehow it is still staying true to Perl's rather pragmatic and, if I may say so, libertarian approach to software developing. I personally love raku's "grammars" most because they render writing parsers a routine job, it's amazing and no other programming language provides such a feature.

If you're interested I strongly suggest you to check out Brian D Foy's book on Raku: https://www.oreilly.com/library/view/learning-perl-6/9781491....
