+  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.
