Thank you for clearing that up > In the case of om.core/value the value may well be stale > > - thus deref - but even then the value may have been deleted. > With om.core/value the user can rely that only the value /she can see/ could be deleted (if it is still up to date), because it is consistent with what was rendered to her. With deref, a value that /she has not yet seen/ could be deleted, because it could have been changed but not yet rendered.
