I don't understand why you throw exceptions from an autoload handler. IMO,
an autoload handler should just define the class if it can access it, and
that's all. I even think that exceptions should be disabled when calling
autoload handlers.
IMHO, if you die() from your handler, you become incompatible with
spl_autoload(), as you cannot know if another handler can resolve the
requested symbol.
