YAMLObject are not directly instantiated so they don't need their own instance attribute (i.e. an own dict). Because of that they should define an empty slots and let subclasses decide whether they want arbitrary instance attributes or not:

The same is basically also true for YAMLObjectMetaclass but I doubt there is much use for this in practice.

In the next Ubuntu release we will be using gcc4.6. pyyaml fails to build with it. The failure is:

Function `PyCObject_FromVoidPtr' implicitly converted to pointer at ext/_yaml.c:20301 Function `PyCObject_FromVoidPtr' implicitly converted to pointer at ext/_yaml.c:20301
