OK.  And it seems C# does the same thing, from what others are saying.

Unfortunately, we don't have a distinct scope-resolution operator (like  
::) so there wouldn't be a way to do this without casting to the  
interface, but I suppose in the cases where you are doing this, you aren't  
generally using the object directly, only through an interface.
