+info: |
+  ArrayBuffer.prototype.transfer ( [ newLength ] )
+
+  1. Let O be the this value.
+  2. Perform ? RequireInternalSlot(O, [[ArrayBufferData]]).
+  3. If IsSharedArrayBuffer(O) is true, throw a TypeError exception.
+  4. If IsDetachedBuffer(O) is true, throw a TypeError exception.
+  5. If newLength is undefined, let newByteLength be
+     O.[[ArrayBufferByteLength]].
+  6. Else, let newByteLength be ? ToIntegerOrInfinity(newLength).
+  7. Let new be ? Construct(%ArrayBuffer%, « 𝔽(newByteLength) »).
+  8. NOTE: This method returns a fixed-length ArrayBuffer.
+  9. Let copyLength be min(newByteLength, O.[[ArrayBufferByteLength]]).
+  10. Let fromBlock be O.[[ArrayBufferData]].
+  11. Let toBlock be new.[[ArrayBufferData]].
+  12. Perform CopyDataBlockBytes(toBlock, 0, fromBlock, 0, copyLength).
+  13. NOTE: Neither creation of the new Data Block nor copying from the old
+      Data Block are observable. Implementations reserve the right to implement
+      this method as a zero-copy move or a realloc.
+  14. Perform ! DetachArrayBuffer(O).
+  15. Return new.
