Fellow monks, I seek opinion.

I've written a custom module to automate deployment of some fairly complex config. My boss opined that it would be nice if the auto deployment was contained in a single file rather than a separate script and module. So I take my DataMethods.pm file and >> it onto the end of 'install.pl', then remove the 'use DataMethods' from the script part to see what happens. What happens is that everything works fine apart from inheritance. For example:

##############inheritest.pl#######################
#use mammal;

my $object = mammal::badger->new;
print $object->hunt;
print $object->snuffle;

##############################################
package mammal;
use vars qw(@ISA);
sub new
{
        my %object = ('blood'=>'warm');
        return bless \%object;
}

sub snuffle
{
        return "Snuffle";
}


package mammal::badger;
use vars qw(@ISA);
@ISA = qw (mammal);

sub new
{
        my %object = ('stripes'=>'true');
        return bless \%object;
}

sub hunt
{
        return "for worms";
}

1;

This simple example script complains that method 'snuffle' doesn't exist, but runs method 'hunt' successfully.

I know this isn't exactly a normal approach to writing OO perl, but the effect is interesting. Anyone care to comment/set me right?

Perl version is 5.005_51 BTW
