I think we can't solve this logical paradox because it contains self-contradictory requirements. Here is the command that illustrates this paradox. What should this command print? C-x p p ... C-h v default-directory RET Like Schrödinger's cat, it belongs simultaneously to both classes: 1. wants to print the new value of default-directory because 'C-h v' is the next command for which the value of default-directory was explicitly set. 2. wants to print the original value of default-directory because 'C-h v' was invoked in the buffer where the value of default-directory should stay unchanged.
