+The `dict` method takes kwargs and creates a dict from that. If we want to pass an object into it the object implement the `__iter__` method.
+We can use `vars` to make that easy:
+```
+def __iter__(self):
+  for k, v in vars(self):
+    yield k, v
+```

+To have a class behave as a dict it's possible to add the two magic methods `__getitem__(self, key)` and `__setitem__(self, key, val)`.
