That good to know.  FlexJS already supports what Flex users think of as

I think annotations are something different, and this thread about
@externs or [Externs] is about something more like annotations at act as
preprocessors that generate first-class data structure on the class.
Metadata is just additional data that requires a special API to access at

I don't want to take on annotations in the compiler right now.  We have
plenty to do, and having a few optional ASDoc/JSDoc tags is the path of
least resistance for me.
