I have uploaded the latest draft of the spec for JEP 325 at http://cr.openjdk.java.net/~gbierman/switch-expressions.html
Changes from the last version: * Supports new -> label form in both switch expressions and switch statements * Added typing rules for switch expression * Restrict the type of a selector expression to not include long, double and float as previously proposed * Misc smaller changes from community feedback (thanks!) Comments welcomed!
