(* 
   [array] is the type of one-dimensional, mutable, zero-based
   constant-time-access arrays with elements of type Word8.word, that
   is, 8-bit words.  Arrays a1 and a2 are equal if both were created
   by the same call to a primitive (array0, array, tabulate, fromList).

   All operations are as for Array.array.
