No. The type of e.g. T.c is the same as the type of some other instance of `test`.
Armed only with a class reference to a `test` object, you cannot tell where it is referenced from.
I think you need to be more specific about what you want to do. I have a feeling you are not understanding how classes work in D (they are not stored inside an object or struct, but rather on the heap, and the member variable is simply a reference to that item).
