More than that, IMO.  Here is the Exception declaration for Ares (note 
that Error has been removed completely):

class Exception : Object
{
     char[]      msg;
     char[]      file;
     size_t      line;
     Exception   next;

     this(char[] msg, Exception next = null);
     this(char[] msg, char[] file, size_t line, Exception next = null);
     char[] toString();
}
