+Changes for `weakref.WeakKeyDictionary.update()`:
+
+* Removed code for updating `WeakKeyDictionary` objects by keyword arguments. This did not work correctly because weak references to `str` objects are not supported;
+* Added clear exception that keyword arguments are not supported in `update()` method;
+* Added test case.
