Never thought I'd hear you say that :-)

Well, it could be made user-selectable, right Bennett? Do you envisage
being able to say
use Fatal qw(Arithmetic IO etc)
using classnames that fall out of RFC 80? Therefore the default (to get
the current behavior) would be that some of the classes had Fatality
enabled and others didn't?
That would at least document and expose the ugly inconsistency :-)
