( #3333=superdoc: print w/ replies, xml ) Need Help??
It gets more interesting! I thought I would throw a SIG{DIE} in there just to see where the route goes and got a very odd result (note the double S):
perl -we "sub fail{die 'test'}; END{ print qq'\nF\n'; fail() }; $SIG{__DIE__} = sub{print qq!\nS\n!; fail()}; fail()" S test at -e line 1. F S S test at -e line 1.
Update

I like line numbers, so I wrote this up as little program:

#!perl -w use strict; my $counter = 0; sub fail{ ++$counter; print "$counter: Fail called.\n"; die "DEATH ". +__LINE__ ."\n" } END{ ++$counter; print "$counter: End called.\n"; fail() } $SIG{__DIE__} = sub{ ++$counter; print "$counter: SigDie called.\n"; f +ail() }; fail()
and the output:
1: Fail called. 2: SigDie called. 3: Fail called. DEATH 4 4: End called. 5: Fail called. 6: SigDie called. 7: Fail called. 8: SigDie called. 9: Fail called. DEATH 4
