+/* Static method object */
+
+/* A static method does not receive an implicit first argument.
+   To declare a static method, use this idiom:
+
+     class C:
+         def f(arg1, arg2, ...): ...
+	 f = staticmethod(f)
+
+   It can be called either on the class (e.g. C.f()) or on an instance
+   (e.g. C().f()); the instance is ignored except for its class.
+
+   Static methods in Python are similar to those found in Java or C++.
+   For a more advanced concept, see class methods above.
