[jira] [Commented] (GROOVY-11229) Support pattern matching for `instanceof`

    [ https://issues.apache.org/jira/browse/GROOVY-11229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17791843#comment-17791843 ] 

Daniel Sun commented on GROOVY-11229:
-------------------------------------

Let me refine the ticket according to comments later, it is hard for me to edit with my smart phone.

 {{o instanceof Point(int x, int y) p}} will have a pattern variable {{p}}. Even if Java does not support it, Groovy could support it.

As for VariableExpression, could you elaborate your suggestion by some examples? I wonder what the AST looks like.
