Question

Why can\'t i define a variable recursively in a code block?

scala> {
     | val test: Stream[Int] = 1 #:: test
     | }
:9: error: forward          


        

Answer 1

I'll add that when you write:

object O {
  val x = y
  val y = 0
}

You are actually writing this:

object O {
  val x = this.y
  val y = 0
}

That little this is what is missing when you declare this stuff inside a definition.
