I recommend making sure that you have tested this with some html tests running
in a browser (let me know if you need help finding the right test.py options).

Also, make sure to test:

-cdart2js -rd8 --host-checked dart2js_native

   }
   listener.endReturnStatement(hasExpression, begin, token);
   // TODO(ngeoffray): expect a ';'.
