That's always been one of my peeves.  At least, ever since I discovered 
that preventing such common C typos as

     if (...);
     {
         ...
     }

isn't implemented by disallowing ";" as a statement altogether, even 
though at the time there was nothing in the spec to _allow_ it.

Walter once claimed that it's useful for automatically generated code. 
Though I'm still not quite sure how.
