So you only have one instance of the object? That's known as a singleton.

You could also create a static class. 

package StaticClass;

my $attrib = '...';

# print StaticClass->method();
sub method {
    my ($class) = @_;
    return $attrib;
}

But I like returning an object since it provides a nice upgrade path. 

package SingletonClass;

my $singleton;

sub new {
    return $singleton ||= bless({
        attrib => '...',
    });
}

# print $obj->method();
sub method {
    my ($self) = @_;
    return $self->{attrib};
}

1;

Shouldn't this be posted in Meditations?

It's a question, so SoPW is definitely appropriate. I don't mind seeing questions meant to illicit discussion in Meditations, though. Both sections are appropriate for some posts.
