Data::Dumper generates a little 'extra' code for you. Combining Chromatic's fix and removing the junk turns the trick:
use strict;
use warnings;
use Data::Dumper;
my $obj = bless {this => 1, that => 1};
my $fileStr;
open my $out, '>', \$fileStr;
(my $dumpData = Data::Dumper::Dumper($obj)) =~ s/^\$\w+\s*=\s*(bless\(
+.*\))/$1/sm;
print $out $dumpData;
close $out;
open my $in, '<', \$fileStr;
my $str = do {local $/; <$in>};
close $in;
my $newObj = eval $str;
$obj->doIt ();
$newObj->doIt ();
sub doIt {
my ($self) = @_;
print "$self->{this} + $self->{that} = @{[$self->{this} + $self->{
+that}]}\n";
}
Prints:
1 + 1 = 2
1 + 1 = 2
True laziness is hard work
