That example does not need `Ractor`.
Yes, you are right, it actually doesn't need Thread either, and is simply about
calling a block in a loop and how to break the loop from the called block:
`proc { break 3}.then { |p| loop { p.call() }}` raises exception, and `proc { raise
StopIteration, 3 }.then { |p| loop { p.call() }}` returns `nil`, etc.

Feature #20444: Kernel#loop: returning the "result" value of StopIteration
doesn't work when raised directly

There was a
https://bugs.ruby-lang.org/issues/11498 a while ago which was merged in, but I
was surprised to find out that raising `StopIteration` in a loop like
`loop { raise StopIteration.new(3) }`
returns nil and not 3.
