Thanks for the reply. I am trying to do just that ( $class->SUPER::method() ):

  # [...]
        my $to_execute = "SUPER::$method_name";
        @parent_slots = $self->$to_execute();
  # [...]

I tried changing it from $self to $class, to no avail (same error).

$class vs. $self.
Consider this most trivial class:

package Trivial;
sub new {
   my $class = shift @_;
   ...
   return bless $self, $class;
}

sub some_method {
   my $self = shift @_;
   ...
}
...

# in your program that uses Trivial:

my $instance = Trivial->new(..);
my $instance->some_method(..);

In the constructor (new), @_ is shifted into $class. This is the name of the package, in this case Trivial.

When calling some_method(), @_ is shifted into $self. Here, $self is a reference to the calling object, $instance, which is of class Trivial.

Although i didn't specifically look, there is surely much more detailed documentation on perlmonks. In any case, a good way to remember what is being sent, look at what is to the left of the arrow "->" operator.

But really, that is a quick and dirty answer that doesnt really tell whats going on. So check out the docs, or Damian Conway's Object Oriented Perl for some very detailed explanations.

Thanks again for the input. I'm familiar with everything you said, and I do have Damian Conways' OOP (although I haven't read it all yet).

In fact, without using Class::MethodMaker, I can write everything by hand and it works like I want it to. Here is (nearly) the same code, but without MethodMaker:

#!/usr/bin/perl
use strict;
use warnings;

#####################################################################
##  Bug
#####################################################################
package Bug;
sub new { bless {}, shift }
sub required
{ 
    my @required = ( 'id', 'type', 'description' ); 
    return @required;
}

#####################################################################
##  FixedBug
#####################################################################
package FixedBug;
use base ( 'Bug' );
sub new { bless {}, shift }
sub required
{
    my @required = ( 
                    'date_fixed', 'repairer', 
                    shift->SUPER::required() 
                   );
    return @required;
}

#####################################################################
##  Main
#####################################################################
package Main;
my $fixed_bug = FixedBug->new();
print join( ', ', $fixed_bug->required() ) . "\n";
