+"""
+
+    Base Idea:
+        - to have a queryset function that easily allows you to build some sort of "pure class" in a queryset.
+        - make it able to seamlessly use annotation functions
+        - allow callback modication of data, which is needed if your dataclass is frozen.
+    
+    By default the PureManager and PureQuerySet will use PureDataclass as handler, expecting your pureclass to be a dataclasses.dataclass type.

+    @dataclass
+    class MyClass

+    
+    SomeModel.objects.filter(...).exclude(...).purify(MyClass, some_relation=F('some__model__relation'), next_id=Lambda(lambda x: x.get('id')+1))
+    
+    This allows you to move an iterator into another layer, where it either can be consumed, or used as an input for another queryset call,
+    but still guaranteeing, that regular usage of the iterator will not yield any smart object.
+    It is good if you want to build a best-of-both-worlds approach for subquery-capable repository pattern, which is one of the biggest issues if you want
+    to keep your business logic out of the repo layer, but still want to utilize djangos queryset mechanics properly.
