Ractor::MovedObject

        # Ractor::MovedObject < BasicObject

(from ruby core)
---
A special object which replaces any value that was moved to another
ractor in Ractor#send or Ractor.yield. Any attempt to access the object
results in Ractor::MovedError.

    r = Ractor.new { receive }

    ary = [1, 2, 3]
    r.send(ary, move: true)
    p Ractor::MovedObject === ary
    # => true
    ary.inspect
    # Ractor::MovedError (can not send any methods to a moved object)
