any way to make this cleaner?

unclean creator in companion.scala

abstract class SuperClass {
  var initialized = false

  def initialize {
    initialized = true
  }
}

abstract trait MetaClass[A <: SuperClass] { self: A =>
  def apply(): A = {
    val obj = newInstance
    newInstance.initialize
    obj
  }
  protected def newInstance: A
}

object Subclass1 extends SuperClass with MetaClass[Subclass1] {
  def newInstance = new Subclass1()
}

class Subclass1 extends SuperClass {

}

object Subclass2 extends SuperClass with MetaClass[Subclass2] {
  def newInstance = new Subclass2()
}

class Subclass2 extends SuperClass {

}
