+  22.2.3.5 %TypedArray%.prototype.copyWithin (target, start [ , end ] )
+
+  %TypedArray%.prototype.copyWithin is a distinct function that implements the
+  same algorithm as Array.prototype.copyWithin as defined in 22.1.3.3 except
+  that the this object's [[ArrayLength]] internal slot is accessed in place of
+  performing a [[Get]] of "length" and the actual copying of values in step 12
+  must be performed in a manner that preserves the bit-level encoding of the
+  source data.
