I agree it was a combination of Raku and Ruby. As far as I'm concerned, Ruby deprecates Perl 5. It fills the same niche while avoiding a lot of the absolutely crazier parts of Perl (no shade; Perl was designed in a far different time and place). If you know Ruby, there is essentially zero reason to learn Perl. I have fond memories of the language, it was the first one I wrote professionally, but never again.

Raku being in such an indeterminate state for so long was an eternity for it to lose mindshare to Ruby.
