While I agree a nested "@disable this" struct inside a struct should  
disable default construction of the outer struct, a class *requires*  
initialization, and a default constructor is called explicitly (and can be  
defined!)  We are talking two different worlds here.

I think the above should be accepted.  I'm not sure how feasible it is,  
since it requires code path analysis.
