Ok. Would you consider any solution, or is that a "leave it 
broken"?

I think I can find a way around the problem for my purposes in 
the short term. However, for other people implementing custom 
types I think it is important, it's a dirty corner that needs 
sorting out. The more you get to know D, the more of them you 
find, the more frustrating it gets seeing they aren't likely to 
get fixed...
