+  22.2.3.23.1 %TypedArray%.prototype.set (array [ , offset ] )
+
+  1. Assert: array is any ECMAScript language value other than an Object with a
+  [[TypedArrayName]] internal slot. If it is such an Object, the definition in
+  22.2.3.23.2 applies.
+  ...
+  10. Let targetLength be the value of target's [[ArrayLength]] internal slot.
+  ...
+  17. If srcLength + targetOffset > targetLength, throw a RangeError exception.
