The topmost exception class is Throwable:

   http://dlang.org/library/object/Throwable.html

As mentioned there, there are only two descendants of it: Error and 
Exception.

There is nothing else that can be said beyond that. Any function is free 
to throw any type as long as it is part of the hierarchy above.
