|Or: Is there any reason to downgrade it back to 'Array'?

It depends on how you define the behavior:

  if first(2) means "gives first two values (packed in array) from the
  original array", it should be Array.

  if first(2) means "returns subarray from the original array with
  first two values", it should be A.

I vote for the former.
