+Ensure objects defined in gitlab.v4.objects have REST* as last item in class
+definition
+
+Original notes by John L. Villalovos
+
+An example of an incorrect definition:
+    class ProjectPipeline(RESTObject, RefreshMixin, ObjectDeleteMixin):
+                          ^^^^^^^^^^ This should be at the end.
+
+Correct way would be:
+    class ProjectPipeline(RefreshMixin, ObjectDeleteMixin, RESTObject):
+                                      Correctly at the end ^^^^^^^^^^
+
+
+Why this is an issue:
+
+  When we do type-checking for gitlab/mixins.py we make RESTObject or
+  RESTManager the base class for the mixins
+
+  Here is how our classes look when type-checking:
+
+      class RESTObject(object):
+          def __init__(self, manager: "RESTManager", attrs: Dict[str, Any]) -> None:
+              ...
+
+      class Mixin(RESTObject):
+          ...
+
+      # Wrong ordering here
+      class Wrongv4Object(RESTObject, RefreshMixin):
+          ...
+
+  If we actually ran this in Python we would get the following error:
+         class Wrongv4Object(RESTObject, Mixin):
+    TypeError: Cannot create a consistent method resolution
+    order (MRO) for bases RESTObject, Mixin
+
+  When we are type-checking it fails to understand the class Wrongv4Object
+  and thus we can't type check it correctly.
+
+Almost all classes in gitlab/v4/objects/*py were already correct before this
+check was added.
