I was actually thinking something similar. Have never heard of 
that requirement before. You're serializing the object, not the 
class, and the static variable doesn't belong to the object (in 
many languages) but the class. I guess D looked at Java? Have no 
evidence of that atm tho.

That doesn't mean D *should* "do what Java does" ofc.
