+ A Map constructed with an empty iterable argument does not call set.
+info: |
+ Map ( [ iterable ] )
+
+ When the Map function is called with optional argument the following steps are
+ taken:
+
+ ...
+ 8. If iter is undefined, return map.
+ 9. Repeat
+ a. Let next be IteratorStep(iter).
+ b. ReturnIfAbrupt(next).
+ c. If next is false, return map.
