Do static variables in class consume memory of instances?

[Mark Lagodych]

[D documentation](https://dlang.org/spec/attribute.html#static) 
says:
> Static data has one instance per thread, not one per object.

Do static variables consume *any* memory in instances, perhaps 
just for pointers to the variables? Or does compiler 
automatically convert `someObject.someStaticMember` to 
`SomeClass.someStaticMember`?
