I'm not too sure. I wrote this (first time messing w/ iheritence w/ perl), and C2 obviously inherited the method printWorld even though printWorld isn't passed the invocant of printGoodBye.

C1.pm:
******* 
package C1;

sub new {
    my $class   = shift;
    my $self    = {};
    return bless $self, $class;
}

sub printGoodBye{ print "Goodbye @_ "; printWorld(); }
sub printWorld{ print "World\n @_"; }

1;
END {}

C2.pm
****** 
package C2;
use base ("C1");

sub new {
    my $class   = shift;
    my $self    = {};

    return bless $self, $class;
}

sub printHi{ print "Hi\n"; }

1;
END {}

o.pl
**** 
#!/usr/bin/perl

use C2;

$bob = C2->new();
$bob->printGoodBye();

exit 0;

Let me know if I'm wrong, but this sure looks like it's inheriting something w/o $self being passed to me. Mark
