Id numbers vs names

Using long id is convenient and safe when dealing with dynamic 
objects or parallel stacks or cards that have objects with same names 
and an alternative to fully qualified control references. Otherwise, 
using names is usually better. In my experience at least. But object 
ids should not change by themselves. At least I do not recall such an 
instance.
