I agree that the things that are not working here ought to work, and I'll investigate. Meanwhile, one point to note: although   matrices b.M = array(0) works, and achieves the same effect. (But they should both work.)

Both series and lists can be put into bundles only for transport purposes (objects of both sorts are actually stored in the bundle as matrices). You have to pull these things out (in the context of a suitable dataset) to work with them qua series or lists.
