in thread Module ( method ) alias ?

Thanks for answering. However seems work out a bit weird..

ModB.pm

package ModB; use parent qw'ModA'; sub new { my $c = shift; return $c->SUPER::new ( @_ ) ; } 1;

ModA.pm

package ModA; sub new { return bless {}, shift } sub p { print @_ } 1;

main.pl

use ModB; my $b = ModB->new(); $b -> p ( "World!" ) ;

It prints ModB=HASH(0x182a5e4)World!. Don't know what am I missed. Also, could you explain a little what is SUPER:: referring to? Is it refer to where parent declared? And how can I inherit other methods with other method name?

Thanks again!

    The first two lines do it all, all the others are only if you want to change something , like swap AudioType with VideoType ), Modern Perl and perlootut explain everything else, just use Ctrl+F to search
      Haha! yes, I got it now. And the problem of my sub p was that I forgot to shift the class ref, so it prints the ref address. Thanks again!
