Proof of concept

Nashorn is a lightweight, high-performance, JavaScript runtime that permits embedding JavaScript in Java applications. This was created for Java 8 and replaced the previous JavaScript scripting engine that was based on Mozilla Rhino. Nashorn already has this functionality. It provides linkage between high-level operations on any object of unknown types, such as obj.something, where it produces the following:

INVOKEDYNAMIC "dyn.getProp.something"

The dynamic linker springs into action and provides, when possible, the appropriate implementation.
