I believe, if I'm not mistaken, that this is often referred to as a singleton. I believe you can do something like so:

package A;
my $obj = undef;
sub new {
    my $class = shift;
    unless (ref $obj eq 'A') {
        # initilize object...
        $obj = bless \%self, $class;
    }
    return $obj;
}

Now both main and B can call the same instance of A by just:

use A;
my $obj = new A();

... in theory :) This is UNTESTED code and someone is allowed to thwack me in the back of the head soundly if I am missing something here.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
• Want more info? How to link or How to display code and escape characters are good places to start.
