edit: don't try to use the $SIG{__DIE__} for this. It won't work.

Care to elaborate? Surely it won't work if somebody else fiddles with $SIG{__DIE__}, just like overriding CORE::GLOBAL::die won't work if somebody else fiddles with it at same time.

perlvar sais:

Due to an implementation glitch, the $SIG{__DIE__} hook is called even inside an eval(). Do not use this to rewrite a pending exception in $@, or as a bizarre substitute for overriding CORE::GLOBAL::die(). This strange action at a dis‐ tance may be fixed in a future release so that $SIG{__DIE__} is only called if your program is about to exit, as was the original intent. Any other use is deprecated.
