Oracle Java language architect Brian Goetz, consulting engineer John Rose and Oracle Labs software architect Guy Steele publicized the first draft of their “State of the Values” proposal http://cr.openjdk.java.net/~jr... describing their overall approach to adding value types or user-defined primitives to the JVM instruction set. The engineers view value types as a way to build new value-based data structures integrated into the JVM that could enable Java support for features such as numerics, algebraic and native data types, tuples, cursors and flattening.
