This is cool to see. The use v5.36 defaults seem reasonable. The n-at-a-time iteration over a hash is pretty neat. I like the addition of defer, and by extension finally blocks. There are a few other things that look interesting.
Seems like the Perl Steering Council is having a positive impact on moving the language forward.
I still hold out hope that raku will gain in popularity but I guess improving Perl5, and eventually Perl7, is the next best option. Better yet, why not both?
