description: >
  Returns undefined if key has a numeric index and object has a detached buffer
info: |
  [[Get]] ( P, Receiver )

    If Type(P) is String, then
      Let numericIndex be ! CanonicalNumericIndexString(P).
      If numericIndex is not undefined, then
        Return ! IntegerIndexedElementGet(O, numericIndex).

  IntegerIndexedElementGet ( O, index )

    Assert: O is an Integer-Indexed exotic object.
    Assert: Type(index) is Number.
    Let buffer be O.[[ViewedArrayBuffer]].
    If IsDetachedBuffer(buffer) is true, return undefined.
