Right.  But even if you're not worried about stupidity, it's useful to 
have it fail in an explicit way as early as possible, rather than later 
on.  With that addition, the moment you try to create an instance of an 
abstract class, you get an exception.  Even if it's just a typo, and not 
severe negligence, that helps the problem get fixed sooner, rather than 
later.
