Keep in mind that just a couple of posts up the thread, WM asserted that
|| Empty is ∩{E(k) : k ∈ ℕ}
No sane discussion about a claim is possible with someone who will
assert and deny an unambiguous statement of that claim. He needed the
fact that the intersection is empty to cover up up another false claim
he'd made, but he'll deny that it's logical or provable just as easily
as he'll assert it.
