RE: A common base exception object for Perl - RFC

["Redford, John" <John.Redford@fmr.com>]

As mentioned elsewhere, I already have ref-array exceptions. I or someone
else could easily have blessed non-Exception exceptions. I would strongly
encourage always checking for $@->isa('Exception') before calling methods of
Exception on $@.

Even without dodgy pseudo-SIG processing,

	blessed $@ and $@->croak

should do. The whole point of all this is that if C<$@> isn't a string,
it's an Exception or a subclass thereof... (Anybody using a prior
exception system will already have code to handle it.)
