This is a followup to Can I serialize an object and have it remember it's type?. Eventually this has applications for serialization, but for now I just want to be able to dump an object and get it back using eval, which I was told I should be able to do. This is my code that doesn't work.
use warnings;
use strict;
use Data::Dumper;
use Test::More qw(no_plan);
package Foo;
sub new {bless {'a' => 1}, $_[0]};
package main;
my $foo = Foo->new();
my $foo_dumped_evaled;
$foo_dumped_evaled = eval(Dumper($foo));
isa_ok($foo_dumped_evaled,'Foo'); #fails
$foo_dumped_evaled = eval{Dumper($foo)};
isa_ok($foo_dumped_evaled,'Foo'); #fails
$foo_dumped_evaled = bless( {
'a' => 1
}, 'Foo' );
isa_ok($foo_dumped_evaled,'Foo'); #fails
print Dumper($foo);
Output from perl dumperIntro.pl > output.txt 2>&1:
not ok 1 - The object isa Foo
# Failed test (dumperIntro.pl at line 14)
# The object isn't defined
not ok 2 - The object isa Foo
# Failed test (dumperIntro.pl at line 17)
# The object isn't a reference
ok 3 - The object isa Foo
$VAR1 = bless( {
'a' => 1
}, 'Foo' );
1..3
# Looks like you failed 2 tests of 3.
Any ideas? Thanks for your help!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
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).
