When working on this, I was mightily surprised when it turned out that derived 
types suffered the same problem as functions - if even intrinsic types are 
affected, then Paul's approach is by far superior to my attempt. As I 
understand it, all issues of this kind would be fixed in one go.

Paul, any progress? :)
