Say I have a method like so:

   sub _setup_dbh {

      my $self = shift;

      $self->{'_dbh'} =
         DBI->connect( $dsn, $username, $password );

      return $self->{'_dbh'};

   }
[download]

and an accessor like so:

sub get_dbh {

   my $self = shift;

   return $self->{'_dbh'};

}
[download]

Which means some client code can do the following:

$dbh = $foo->get_dbh;

$dbh->prepare( "blah blah whatever" )
[download]

That's all fine... HOWEVER.... I want to throw another method into that $dbh object; something like:

sub dbq {

   my $self = shift;
   my $sql  = shift;

   my ( $sth );

   $sth = $self->{'_dbh'}->prepare( $sql );

   $sth->execute;

   return $sth;

}
[download]

How do I get that 'dbq' method into that _dbh object? So the client code could do:

$dbh = $foo->get_dbh;

$dbh->dbq( "blah blah whatever" );
[download]

I of course still want to keep all the other methods that the _dbh object has. Also, the example is just for illustration purposes... basically, I have a class "foo" that instantiates an object of some other completely external class, "bar"; but it's imperative that I stuff that object "bar" with my own method that is defined within my class "foo". Your kindly assistance is most appreciated!
