What is the behaviour of an *uncaught* exception, particularly with respect to CHECK/END/LEAVE/LAST blocks, destructors, overloading of the stringify operator on exception objects, the order in which these things are executed, and the exit code of the process? (And anything else that I haven't thought of)
Perl 5's behaviour in this respect is largely undocumented and doing things during exception-triggered global destruction has a habit of generating messages about attempting to free unreferenced objects, or just crashing the interpreter entirely, and I can't see anything in the synopses about it. A closely related question here: exactly how much can I assume has already been executed when writing destructors and ALAP blocks? Do I have to guard against some of my data mysteriously transmuting into undef?
