Efficient support of dynamic inheritance for class- and prototype-based languages

► We define language-neutral dynamic inheritance for both class- and prototype-based object models. ► The semantics has been included as part of a production JIT-compiler virtual machine. ► The resulting virtual machine has been evaluated to provide significant runtime performance benefits with low memory consumption. ► Our platform supports both dynamically and statically typed languages, allowing a direct interoperation between them. ► Backward compatibility with existing. Net applications is maintained.
