Not sure what you are getting at here, Bob. A ScopeGuard object is created and assigned to a variable; that variable is never used (not directly anyway) after the assignment, and that's what triggers the warning. Using the variable (to Dismiss() the guard, for example) obviates the warning. - Dennis
