My thoughts:<p>- RBS: meh... might get more useful in the future (in 2-5 years maybe).<p>- Ractor: Wohooo! I'm writing a DAG library where I was thinking of implementing something like this, good to know I can use it and get real parallelism on top.<p>- Scheduler: :shrug: don't know about this one, might be relevant with future concurrent ruby code, any ideas?<p>- Rightward assignment: it's a bit awkward but I see the use case, just wish we had the pipe operator too like in Elixir.<p>- Endless method: this one is cute, I love it!<p>- Find pattern: oh boy, code reviews are going to be interesting now!<p>- Hash#except: yes, definitely a welcome one.<p>- Memory view: if this helps with numpy style gems it will be great!<p>- `send(:"do_#{ meth }", ...)`: don't do meth kids! (it's a joke!)... seems like a reasonable feature.<p>- `order of backtrace had been reversed`: good! it was confusing...<p>- Promote default gems to bundled gems (rexml): I like this one, if only nokogiri was a stdlib gem or part of core, imagine how much time would be saved instead of having to compile it every time in a `bundle install`.<p>- `Promote stdlib to default gems`: what does this mean? Do I now have to add `gem "securerandom"` to Gemfiles instead of having it by default and just needing to require it?<p>- Mjit improvements: can't wait to try it!<p>Overall, I'm delighted!
