- This paper is significant because it describes the first approach to enable efficient and thread-safe object representations in dynamic languages. With it, dynamic languages can offer safe shared memory access to objects without preventing dynamic addition, removal, and type-changes of fields for performance reasons. The performance benefits have been shown on well-established benchmarks and the Sidekiq library, widely used in commerce (e.g. Netflix and GitLab). Our technique has been adopted for defining the concurrent memory model for objects in the Ruby community. Oracle patented the technique and use it in their Ruby and Python implementations (US2017/0277467).
