If you are talking about the goog.base() inside the constructor body, it always has to be there unless the class inherits from Object. This is needed to simulate ActionScript semantics: if your constructor does not contain a super(...) statement, an implicit one is added as the first statement. If no constructor is specified at all, a no-arg constructor simply calling super() is implicitly added (which leads to a compiler error if the super class does not allow no args for the constructor). Of course, all this implicit stuff is not automatically done by JavaScript (as it is unaware of our class system), and so has to be added to generated code explicitly. I guess when you are visiting ABC, not AST, the implicit code is already present, in other words, you should never find a constructor not doing a super() call in ABC. But mind that I know nothing of ABC, so this is just a common sense guess.
