For example:
```
scala> case class C()
defined class C

scala> typeOf[C.type].decls
res0: $r.intp.global.Scope = Scopes(constructor C, method toString, method apply, method unapply, method readResolve)

scala> typeOf[C.type].decls.map(_.isSynthetic)
res1: Iterable[Boolean] = List(false, true, true, true, true)
```
