Annotating a primary constructor is pretty ugly. For example:

@Component
class Foo @Autowired()(val bar: Bar) {
  //...
}

It would be nice if you could target what would normally be a class annotation at the primary constructor - for example:

object Annotations {
  type AutowiredConstructor = Autowired @primaryConstructor
}

@Component
@AutowiredConstructor
class Foo(val bar: Bar) {
  //...
}

Action on one ticket will probably have effect on the other one: #4242 / #5647.
