I think I figured it out. There is indeed "something deeper in Scala” :-)
abstract class A {
def a: this.type
}
class AA(i: Int) extends A {
def a = this
}
the above works ok. But if you return anything other than “this”, you will get
a compile error.
abstract class A {
def a: this.type
}

I think it's imitating, for example, how Enum is delcared in Java:
abstract class Enum>
this is done so that Enum can refer to the actual type of the derived
enum class when declaring things like public final int compareTo(E o)
to implement Comparable. The type is redundant in a sense, because
