They might be referring to the update methods:

  val array = new Array[String](10)
  array.update(7, "hello")
  array(7) = "hello" // simply calls out to update

I still fail to see what makes this questionable. It's just syntactic sugar that you don't even need to use, and which is pretty clear when you see it in the wild.

Oh yeah I don't think it's questionable at all, just guessing what they're talking about.
