>
> Using the Visitor pattern allows for a cleaner implementation of toString().
> I have a patch which will remove toString() from all AST classes, and replace
> it with a single toString() in "SimpleNode" which delegates to a
> ToStringVisitor to build the String efficiently.
> This patch can also be used as an example of how to move other business logic
> out of the AST classes into their own visitor classes.
