There's another problem with this work-around -- it breaks in the other
direction!
tin-foil:/tmp glasser$ cat /tmp/localdie
sub i_die {
die "this is why I died";
}
sub i_localize_dollar_at { # This could certainly be DESTROY
local $@;
i_die();
}
eval { i_localize_dollar_at() };
my $error = $@;
if ($error) {
print "The error was: $error\n";
} else {
print "There was no error. (Or was there?)\n";
}
tin-foil:/tmp glasser$ perl localdie
There was no error. (Or was there?)
That is, localizing $@ in DESTROY solves the problem of "an eval inside
the DESTROY hides an error that happened before the DESTROY", but it
causes the problem that it hides an error that happens *in* the DESTROY!
I'm not sure if Alex's patch has this issue too.
