The lie, uhhh, "meme" that Perl and Raku are even "sister languages" is over, per the creators of that lie.
Sorry, but what's your source on that?
Also, there's a question implied by jdporter's question that AFAIK hasn't been addressed yet, but that I've genuinely been curious about: Why do you seem to care so much about this issue, as in, how has Perl 6 affected you directly, personally? Like, just one example might be, have you lost a job because of it? I really don't understand, but I'd like to.
