  [[Delete]] (P)

  ...
  Assert: IsPropertyKey(P) is true.
  Assert: O is an Integer-Indexed exotic object.
  If Type(P) is String, then
    Let numericIndex be ! CanonicalNumericIndexString(P).
    If numericIndex is not undefined, then
      If IsDetachedBuffer(O.[[ViewedArrayBuffer]]) is true, return true.
      If ! IsValidIntegerIndex(O, numericIndex) is false, return true.
      Return false.
    ...
  Return ? OrdinaryDelete(O, P).
