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.
