Subject [jira] [Created] (GROOVY-8582) CLONE - CLONE - Support `var` keyword of Java10 (documentation)

Paul King created GROOVY-8582:
---------------------------------

             Summary: CLONE - CLONE - Support `var` keyword of Java10 (documentation)
                 Key: GROOVY-8582
                 URL: https://issues.apache.org/jira/browse/GROOVY-8582
             Project: Groovy
          Issue Type: New Feature
            Reporter: Daniel Sun
            Assignee: Daniel Sun
             Fix For: 3.0.0-alpha-2, 2.6.0-alpha-4


This is to provide compatibility with:
http://openjdk.java.net/jeps/286 (Java 10)
http://openjdk.java.net/jeps/323 (targeted for Java 11)

Java 10 provides var to allow reduced ceremony by avoiding manifest declaration of types for
local variables for cases where type inferencing can be supported. Groovy already does this
with "def" and has it's own approach for type inferencing within type-checked/compile static
code. With this in mind, it seems to make most sense for Groovy to have "var" as an alias
for "def" rather than closely mimic only the use cases allowed by Java.
