for JEP 236, I'm not sure that we need a visitor anymore along with the 
AST, now that we have lambdas,
a HashMap AST node -> function to execute, is enough.

see for an example of usage
https://github.com/forax/vmboiler/blob/master/script/src/com/github/forax/vmboiler/sample/script/TypeInferer.java#L46

and  the definition of a Visitor
https://github.com/forax/vmboiler/blob/master/script/src/com/github/forax/vmboiler/sample/script/Visitor.java

Note: that this 'new visitor' doesn't need any support method (usually 
named 'accept') defined on the AST node.

cheers,
