+    1. Let O be the this value.
+    2. If Type(O) is not Object, throw a TypeError exception.
+    3. If hint is the String value "string" or the String value "default", then

+    4. Else if hint is the String value "number", then
+       a. Let tryFirst be "number".
+    5. Else, throw a TypeError exception.
