in reply to Overriding CORE::GLOBAL::warn/die

I would not advise overriding any “core” functionality, because of course that would be all-encompassing.

Consider using code such as Exception::Class, which leverages the fact that you can in fact “die” with an object, not merely a text string.

I simply think that it is very inadvisable to make any changes that have “global” ramifications to suit a “app-specific” requirement ... because they expose the entire software (every CPAN module, etc.) to the very considerable side-effects of your change.   If I may opine, “Abandon All Hope, Ye Who Enter Here.”   I’m scrambling away from the very thought of this situation so fast, I don’t even care why it’s not working ...  My spider-sense is going off; my trusty elven sword is glowing bright blue ...

    Your senses do not deceive you! Involved is a tie of STDERR, BEGIN/INIT/END blocks, implicit source filtering (of modules used) by means of unshifting a sub onto @INC, the override of core die ... and I can't remember what else. And most of the time it does its job quite nicely. And when it doesn't ... I remove the use statement and debug the normal way.
