This one feels good. No more stupid comments at the top of files. At least in one repo.
@paracycle @Dagnan @vipulnsward To be fair to this article, the very first version of "chilled strings" did return true when `frozen?` was called on it. It was changed a little bit after that post was published.
@Dagnan It's not, though. It's still opt-in even in 4.0.
@marcoroth_ About the boot performance, as discussed in Hakodate, I'd be interested to look in what it would take to support precompiling templates with Bootsnap, making parsing performance less important.

I wrote answer letter: github.com/ruby/rubygems/…
I wrote some more as a way to fight jet lag, hopefully it's still readable 😅: byroot.github.io/ruby/bundler/2…
@samsaffron And right now we have no way to specify that in the gemspec, all we can do is raise in your face during boot, which isn't ideal.
@samsaffron Well, the proposed `ban` directive does answer that. But while I didn't list it here, optional dependencies are indeed a long requested feature. E.g. in Active Support, we don't force you to install `dalli` or `redis`, but if you do it has to satisfy a certain minimum version.

With the new job, I didn't get much time or energy to blog lately, but I figured I'd use the various downtime while traveling to Ruby Kaigi to write about some of the things I worked on recently: byroot.github.io/ruby/performan…
@nateberkopec It is! Very conveniently located too.
Happy to share that today I'm starting as senior principal at Intercom!
@morgoth85 No downsides here f that works for your app.
I was recently reminded that not everyone fully understand what the frozen string literal magic comment is about. So I figured it was the occasion for another deep dive. byroot.github.io/ruby/performan…
I tried to explain why I don't believe the recent accusations toward my former teammates, as well as how the Ruby and Rails Infra team at Shopify operates and why it can be trusted. byroot.github.io/opensource/rub…

Honored to be back on stage at #RailsWorld in Amsterdam next week to help guide a conversation with @tenderlove, @_byroot, and @hsbt. Still a few days before I lock in the topics. What questions would you love to hear them answer?
Members of the Rails Core and Ruby committer teams come together for a special session on the #RailsWorld stage next week. @tenderlove, @_byroot, and @hsbt will chat with host @robbyrussell about the future of DevEx in the Ruby and Rails ecosystem, and how foundational tools like
@seuros @maciejmensfeld It very much was a mistake and was never necessary. If you follow the PRs you'll see.
