I understand that, but in the context of the example, the tiOPF project has different implementations of the same functionality for different GUI toolkits. So in that case the developer would use the partial namespace unit name (tiMediator or tiListMediator) in the uses clause, and the compiler will figure out which fully quality unit you mean, by looking at the Namespace Scope List. In my other example with using very generic unit names (eg: constants.pas), then you would opt to use the fully qualified unit name in the uses clause to tell the compiler which unit you are referring too. So those are two very different situations and uses of the namespace feature. Like I said, I've never used namespaces personally, but I'm sure more usage examples exist. I think it is quite a useful feature, and should not only be considered "cosmetic unit names".
