Are you aware of jruby?
https://www.jruby.org/
It is ruby running on a Java Virtual Machine. Imposes all downsides of the JVM (try to allocate more that 4GByte per object!) and provides JVMs concurrency model. Currently supports Ruby 3.1 (it claims to support 3.4, read the fine print if your specific feature is supported!)

Since our Todo items are attached to groups, and we’d like to have structured JSON responses where each item is nested within a group, we will build our serializers with Alba. Let’s update the Gemfile:
-
Important: According to the Solid Cache README, when you omit database, databases, or connects_to settings, Solid Cache automatically uses the ActiveRecord::Base connection pool (your primary database).

I see a lot of comments here asking about practical motivations for this feature. One I'll share is that in a gem I help maintain, we benchmark git branches of the gem against `main`, and we also benchmark against multiple other gems that sometimes have namespace collisions with each other. To make this work, we use a third-party gem[0] and an anonymous module trick[1] that are each a bit hacky.
That being said, I have no particular stance on whether this feature is a good change to the language; in a decade of Ruby this is the only situation I can recall that really merited it, and the concerns articulated by byroot and others do resonate with me.
