Comment:

 An unhandled bad_lexical_cast exception gives the message:
 {{{
 terminate called after throwing an instance of
 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast>
 >'
   what():  bad lexical cast: source type value could not be interpreted as
 target
 Aborted
 }}}
 (That example is from Ubuntu.) Throwing an isc::Exception-derived
 exception allows more information to be given as to where the problem
 lies.  The exception also includes the file and line (and the text of the
 message also includes the name of the method in which the exception
 arose.)
