def from[A : ClassTag](it: IterableOnce[A]): ArraySeq[A]
def make[T](x: Array[T]): ArraySeq[T]

Wrap an existing Array into a ArraySeq of the proper primitive specialization type without copying.

Wrap an existing Array into a ArraySeq of the proper primitive specialization type without copying.

Note that an array containing boxed primitives can be converted to a ArraySeq without copying. For example, val a: Array[Any] = Array(1) is an array of Object at runtime, containing Integers. An ArraySeq[Int] can be obtained with a cast: ArraySeq.make(a).asInstanceOf[ArraySeq[Int]]. The values are still boxed, the resulting instance is an ArraySeq.ofRef. Writing ArraySeq.make(a.asInstanceOf[Array[Int]]) does not work, it throws a ClassCastException at runtime.
