In the Carp man pages it states that croak and confess do...
croak - die of errors (from perspective of caller)
confess - die of errors with stack backtrace
but I don't see any difference in how they work.
I wrote a little test program as follows...
use Carp;
print "test1\n";
eval { a(); };
warn $@ if $@;
print "\ntest2\n";
eval { d(); };
warn $@ if $@;
sub a { b(); }
sub b { c(); }
sub c { croak 'croak in c'; }
sub d { e(); }
sub e { f(); }
sub f { confess 'confess in f'; }
... and ran it. It produced the following output....
test1
croak in c at testit line 12
main::c() called at testit line 11
main::b() called at testit line 10
main::a() called at testit line 4
eval {...} called at testit line 4
test2
confess in f at testit line 16
main::f() called at testit line 15
main::e() called at testit line 14
main::d() called at testit line 7
eval {...} called at testit line 7
What is the real difference here?
