+   .. note::
+      By default, if no second argument is provided, :func:`super` uses the first argument
+      of the immediately enclosing function definition, which is ``self`` under normal circumstances.
+      This may lead to unexpected behaviour if used inside nested functions or generator expressions
+      (the latter creates implicit nested functions). The following example will result in an exception::
+
+         class A:
+            def method(self):
+               return 1
+
+         class B(A):
+            def method(self):
+               return list(super().method() for _ in range(3))   # Expected [1, 1, 1] but TypeError will be raised.
+
+      In such cases, you should provide arguments explicitly::
+
+         class A:
+            def method(self):
+               return 1
+
+         class B(A):
+            def method(self):
+               return list(super(B, self).method() for _ in range(3))   # Will return [1, 1, 1].
