Earlier quoted context omitted.
There's no saving Perl 5; it's a legacy language in legacy maintenance mode for good reason. Renaming Raku/Camelia could help that language quit being saddled with the perception that it's also legacy in the same way, though.
What good reason is that?
1. CPAN was great 20 years ago, but it's a joke compared to modern dependency management systems.
2. Functions don't have explicit parameters, and still shift off of @_. (This can be kind of a catch-all for all the "things that are useful for scripts, but suck for programming in the large" design decisions in Perl 5, because I honestly don't remember all of them at this point.)
