Hello monks,

I seek your wisdom in determining the best way to access a package variable of a subclass from within a base class method. I have identified a working solution, but it is ugly and I don't completely understand it. It also uses stringy eval, which I know to be taboo in most cases.

Surely there must be a more elegant (or correct) way for a method in a base class to access the package variables of the subclass that inherited it?

Thanks in advance, and here is some functional example code illustrating what I am trying to accomplish.

m.

#=================
package BaseClass;
#=================
our $ID = 1;

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

sub id {
    my $self  = shift;
    my $class = ref $self;

    return eval "\$${class}::ID";
}

#================
package SubClass;
#================
use base qw( BaseClass );
our $ID = 2;

#============
package main;
#============
my $obj = new SubClass;
my $id  = $obj->id();

print "$id\n";
