Please consider the evolution of the class-level language features:

1. C++ - static member variables
2. Java - static members and static initialization blocks
3. C# - static members and static constructors

I think there is a clear pattern of implementing more and more of the 
object-level OO features on class (static) level. I believe the next 
logical step will be a language support for static destructors. As far 
as meta-progamming is concerned the static features will beef up the 
class level in the object-class-metaclass triad. Again, this is just the 
personal opinion of a "evil" legacy(Java) programmer :-)

Thanks again,
