I had hope there would be a merging (with some compatibility layers and wrapper binaries) allowing to use Raku the same way Perl 5 was used (should not have been _that_ hard, just adding familiar options and special variables)... Now I'm seeing this goes in a total different direction.
Perhaps. Meanwhile, the most recent release of the Inline::Perl5 module of Raku allows one to have code blocks written in Perl inside Raku code, and vice-versa. And of course be able to use any CPAN module from Raku: https://modules.raku.org/dist/Inline::Perl5:cpan:NINE
Nice! I didn't know. But it still does not bring back the classic usage in Perl 5 style, that made intensive use of runtime options as shorthands for looping on all lines of a file etc.
