  Vaidman, in a recent article adopts the method of 'quantum weak measurements
in pre- and postselected ensembles' to ascertain whether or not the
chained-Zeno counterfactual computation scheme proposed by Hosten et al. is
counterfactual; which has been the topic of a debate on the definition of
counterfactuality. We disagree with his conclusion, which brings up some
interesting aspects of quantum weak measurements and some concerns about the
way they are interpreted.
