Appending to an Array stored in an enum case payload: O(1) or O(n)?

If one applies move to a var, one gets the same semantics as let except that one
can begin using the var again after one re-assigns to the var, e.x.:

func f() {
  var x = getValue()
  let _ = move(x)
  // Can't use x here.
  x = getValue()
  // But I can use x here, since x now has a new value
  // within it.
}

I don't know why you think that, since the pitch explicitly mentioned it as being allowed.
