Correction: If `weirdFunction` were defined as if by evaluating `function () {
return this }`, **no**: in such a constructor (more precisely: when such a
function is used as a constructor), `this` is a brand-new "instance"; it can’t
be === to a previously existing object such as `iter`.
(Given how confusing and useless it is, I hope that my intuition ("not a
constructor") is correct.)
