+description: >
+  Returns undefined if key has a numeric index and object has a detached
+  buffer (honoring the Realm of the current execution context)
+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.
