Interesting idea. You could probably put something together around
ClassNameLocator, i.e., a wrapper that given package names, find
interfaces inside those packages that have matching Impl classes. i.e.
public static void bind(ServiceBinder binder)
{
new AutoServiceBinder("my.package.root").bind(binder);
}
