You misunderstood: toggle-debug-on-error is exactly the same as setting
via setq or set-variable.  What Pascal was referring to is that errors
that occur while running post-command-hook cause the corresponding
function to be removed from the hook (to try and prevent the error from
occurring over and over again), so such errors tend to "occur only once".
