for { ... } in your example is the FunctionBody production as defined at http://es5.github.com/#x13 I believe Rhino just uses http://www.jarvana.com/jarvana/view/org/mozilla/rhino/1.7R3/rhino-1.7... as the node type since it allows FunctionDeclarations in any block which is not strictly allowed in ES5. There are additional syntactic constraints around break/continue labels and whether or not an enclosing function/program is in strict mode that are not expressed in that grammar.
