Using subclassing to bung in some arbitrary trait is really terrible. :/ It requires either adding it up high in your class hierarchy, or having to write a custom NoSuchPropertyClass which extends your superclass, so you can then extend it. I'm rather surprised that the group actually considered that sort of code to be appropriate - it's known that it doesn't compose well with other traits-as-superclasses or normal subclassing.
