Nevermind. The reason why the Dumper line didn't work because I have not defined the FIRSTKEY and NEXTKEY functions. 
sub FIRSTKEY {
    my ($self) = @_;
    each %{ $self->{'value'} };
}

sub NEXTKEY {
    my ($self) = @_;
    each %{ $self->{'value'} };
}

Once I added the two functions, then the Dumper worked. But interestingly, how come Perl didn't tell me that the two functions need to be defined at all?
