Hi Joe,

I refer to your proposal: http://mail.openjdk.java.net/pipermail/coin-dev/2009-February/000001.html If your proposal would unchanged be taken into JDK 7, there won't be any compatible way to implement my more general proposal "Extend switch .. case statement for Object types and simple expressions" in future version of JDK !!! --> So switch .. case statement should compare for IDENTITY if not syntactically determined otherwise. --> compare for EQUALITY would also break semantic of existing switch .. case statement.

While pattern matching is a fine feature in some languages, I don't think retrofitting that flavor of facility onto Java much over and above the existing capabilities of the switch statement is the right direction to evolve Java.
