The proposed names are the most useful from my experience, take e.g. these lines, found in the same class: throw new class() implements ServerExceptionInterface {...}; [...] throw new class() implements ClientExceptionInterface {...}; The debugging experience is better mentioning ServerExceptionInterface or ClientExceptionInterface than the namespace of the surrounding class. The file + line info will fo straight to this surrounding class also, so the proposal maximizes the amount of useful info from my experience. Nicolas
