Comment on ``Possibility of quantum mechanics being nonlocal''
  A recent proof, formulated in the symbolic language of modal logic, shows that a well-defined formulation of the possibility mentioned in the title is answered affirmatively. In the paper being commented upon several proposals were made about how to translate this symbolic proof into prose, and it was concluded, on the basis of those proposed translations, that either the proof was invalid or that an unwarranted reality assumption was made. However, those interpretations deviate in small but important ways from the precise logical path followed in the proof. It is explained here how by staying on this path one avoids the difficulties that those deviations engendered.
