+  Creating a new Map object without arguments doesn't throw if `set` is not
+  callable
+info: |
+  Map ( [ iterable ] )
+
+  When the Set function is called with optional argument iterable the following steps are taken:
+
+  ...
+  5. If iterable is not present, let iterable be undefined.
+  6. If iterable is either undefined or null, let iter be undefined.
+  7. Else,
+    a. Let adder be Get(map, "set").
+    b. ReturnIfAbrupt(adder).
+    c. If IsCallable(adder) is false, throw a TypeError exception.
+    ...
+  8. If iter is undefined, return map.
