Carry annotations from interface into generated implementation

See original GitHub issue

Has this been considered? The following is an example use case:

class Foo @AssistedInject constructor(@Assisted val assisted: Bar) {
  interface Factory {
    fun create(assisted: Bar): Foo

to generate a factory implementation annotated with @Reusable:

@Reusable // This line is new
public final class Foo_AssistedFactory implements Foo.Factory {
  public Foo_AssistedFactory() {

  public Foo create(Bar assisted) {
    return new Foo(assisted);

I understand it’s probably a bit questionable since something like this would also leave the interface annotated which may not be desirable, but considering interfaces have no implementation I see no major issue with it, and there may also be other mechanisms to achieve the same goal and don’t have this issue. Thoughts?

Ok! It’s not that urgent. There’s three whole days left this week, and Monday would be fine, too.

I have a patch half-way through for annotations in dagger.* packages. Just need to add/update some tests but I’m afk right now, I’ll have it ready in a few hours

I would like to do a release this week. Let me know how you are progressing and if you want me to take over. We can start with just special casing that annotation.
