Just a question: Does this CL support all forms of serializer described in the
spec? Or only following forms?
- serializer
- serializer type identifier()

[Jens Widell, 2015/03/26 05:34:10]

The base parser supports all forms. Thus CL mostly doesn't care what the
definition looks like, but it will allow all forms.

I added one test each for the two output variations this CL supports.

 
     // Per-method [Exposed] annotation support.
     void alwaysExposedMethod();
     [Exposed=Worker] void workerExposedMethod();
     [Exposed=Window] void windowExposedMethod();
 
     static void alwaysExposedStaticMethod();
     [Exposed=Worker] static void workerExposedStaticMethod();
     [Exposed=Window] static void windowExposedStaticMethod();
