Yes, classes, interfaces, traits, methods, properties, functions.
Unfortunately we can't apply to namespaces as they don't exist after
compile time.

No, there's no Reflection data structure around them and imposing one would
be a serious BC break

Annotation classes would be annotated with @Annotation and their
corresponding @Target (where they could be applied).

No. Annotations by itself is already a big endeavor and including more
stuff would only make it harder to implement/digest/approve.
What if Annotation gets approved, but people want decorator out? More
work...
Nothing prevent us to make a subsequent RFC to support decorators if the
first one gets accepted.
