(* This tactic solves goals about inclusion and disjointness
of masks (i.e., coPsets) with solve_elem_of, taking
disjointness of namespaces into account. *)
(* TODO: This tactic is by far now yet as powerful as it should be.
For example, given N1 ⊥ N2, it should be able to solve
nclose (ndot N1 x) ∩ N2 ≡ ∅. It should also solve
(ndot N x) ∩ (ndot N y) ≡ ∅ if x ≠ y is in the context or
follows from [discriminate]. *)
