Scala: how to inherit a “static slot”?

Question

Well, I\'m learning Scala so this question may be too basic for most people.

In Java I can have a static slot (function or variable) in a class, and then I will have

Answer 1

Afaics, Daniel Spiewak's and Walter Chang's answers appear to provide two separate copies of the all list. I didn't test the following, but I hope this provides the correct outline even it if has errors.

class Person
class Student extends Person

object Person {
  val all: List[Person]
}

then within Student, access via Person.all

If you want to provide access via Student.all then

object Student {
  def all() = Person.all
}

Another way to do it, would allow you to declare the statics (i.e singleton object) in a trait to be inherited.

trait StaticAll {
   object Static { val all: List[Person] }
}

class Person extends StaticAll
class Student extends Person

Then access with StaticAll#Static.all. I think that is correct and not StaticAll.Static.all. Again this is all off the top of my head, I didn't test any this. Please correct my errors.
