scala – 冲突的嵌套继承特征

trait Trait1 { 
  trait Inner {
    val name = "Inner1"
  }
}

trait Trait2 {
  trait Inner {
    val name = "Inner2"
  }
}

class Foo extends Trait1 with Trait2 {
  // I want Concrete1 to be a Trait1.Inner not a Trait2.Inner
  class Concrete1 extends Inner
  val c = new Concrete1
}

object Obj {
  def main(args: Array[String]): Unit = {
    val foo = new Foo
    println(foo.c.name)
  }
}

当我在Trait1和Trait2中混合时,指向Inner似乎默认为我混合的第二个特征的内部类型;所以当我调用Obj的主要方法时,它会打印Inner2.如何在Foo中引用Trait1.Inner？以下所有三个都给出了编译器错误：

class Concrete1 extends Trait1.Inner
class Concrete1 extends Trait1$Inner
class Concrete1 extends Trait1#Inner
