dear brothers and sisters,

while using CGI::Session I learned about Safe.pm. It's used in CGI::Session to savely eval stuff that has been written by Data::Dumper. This works great with normal data structures, but not with objects.

Say I have a Data::Dumper - string containing (among other stuff) an object:

$string = <<'EOM';
    $data = {
          'person' => bless( [
                       42
                     ], 'Person' )
        };
EOM
[download]

When I reval this string like so...

my $mysafe = Safe->new("MySafe");
$mysafe->reval($string);
[download]

...I get a proper object of class Person, but I can't call any of the methods:

Can't locate object method "method" via package "Person" (perhaps you forgot to load "Person"?)

Why is that? Is that a bug or a feature?

P.S. The full code is available

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
