Retrofit of Ractor in Ruby 3.5 to work like one in Ruby <= 3.4 having yield/take

ractor_35.rb

Ractor = Class::new(Ractor){
  def self.new(*args, &b)
    out_port = Ractor::Port::new
    res = super(out_port, *args, &(proc{|_port, *_args|
      Ractor[:out_port] = _port
      _args
    } >> b))
    res.monitor(out_port)
    res.define_singleton_method(:out_port){out_port}
    res
  end
  def self.yield(msg, move: false) # Do not push reserved symbols(:exited and :aborted)
    Ractor[:out_port].send(msg, move: move) # Non-blocking, which differs from the original version
  end
  def take
    case res = out_port.receive
    when :exited, :aborted; out_port.close; value
    else; res
    end
  end
}
  
x = Ractor::new{2.times{Ractor::yield(Ractor::receive, move: true)}; 345}
x.send(123); x.take # => 123
x.send(234); x.take # => 234
x.take # => 345
x.take # => Ractor::ClosedError
