08:06 AM Ruby Feature #22226: Ractor: class/module ownership -- restrict modification to the Ractor that created it

How will autoload work with this?
My understanding would be that autoload will simply not work from ractors, even on classes they own, except via `Ruby::Box`. Is that correct?
Autoloads currently run on the main ractor, so ownershi... rkh (Konstantin Haase)

08:50 AM Ruby Bug #22211: Fiber::Scheduler stalls on Ractor::Port.receive

Interesting!
I've been playing with workarounds in Ruby-land where I have up to one extra thread per Ractor, which executes `Ractor.select(coordinating_port, *ports)` with a backlog of waiting fibers per port, and then uses a `Conditi... rkh (Konstantin Haase)

02:51 PM Ruby Bug #22211 (Open): Fiber::Scheduler stalls on Ractor::Port.receive

Quickly upfront: This might be a duplicate of #20276, and let me know if the official solution is still to launch a thread for each port so it can block (or add some more complex thread orchestration).
Anyway, I think `Ractor::Port#re... rkh (Konstantin Haase)

I assume the final release will have an official .wasm file that ships with it.

09:34 PM Ruby Feature #8947 (Open): make alias, alias_method, attr_* return name of the alias

Now that def returns the method name, it would be handy to have alias/alias_method return the name of the alias:
class Foo
private def foo() end
protected alias_method :bar, :foo
end
Same goes for the attr_* methods:

01:07 AM Ruby Feature #8635: attr_accessor with default block

If this should be added, could you consider adding it with a read-write-lock? rkh (Konstantin Haase)
