That's a storage class, not a type constructor. In D, threadlocal/shared is a difference in the type.
In C#, all attributes live inside the TypeInfo/MethodInfo/etc for the class/struct/method/field/parameter. I don't see this being a problem. I can't think of good use cases where an attribute/annotation should be per-instance at all, particularly with the compile-time power that D has, whereas C# does not have any. Honestly, most uses of attributes in D would be done at compile-time, and I think that's acceptable until/if runtime reflection is put in. If it is needed, it can live inside TypeInfo/MethodInfo, but is (imo) absolutely not needed on a per-instance basis. This is the job of fields or interfaces.
I also do not get why per-instance attributes even exist, as I agree that's what fields are for.
