C<die> is not a class, so I don't understand what "subclassing" it
should mean.  Do you mean, how do you catch an uncaught die?  You
wrap it with an eval and look at $@.  Do you mean how do you replace
the CORE die with your own function?   That's done by importing
into CORE::GLOBAL::die.  Sounds like you are trying to discard
Perl's exception-handling system and write your own, which sounds
like it falls under "Any attempt to build a general exception model
on [$SIG{__DIE__}] should be politely squashed."
