NodeTraversal.Callback
Visits a node in pre order (before visiting its children) and decides
whether this node's children should be traversed. If children are
traversed, they will be visited by
NodeTraversal.Callback.visit(NodeTraversal, Node, Node)
in postorder.
Implementations can have side effects (e.g. modifying the parse tree).
