The `CalledAs` method returns the name of the command or alias that invoked the command -- as long as the command was actually invoked. Otherwise, it returns the empty string. The opens up possibilies for commands to behave differently based on which alias invoked the command (in the same vein as Linux programs which adjust their behavior based on the value of argv[0]).
