Not really, Class->constant won't inherit from Superclass->constant ; it needs to be defined in both.

however $classObject->constant will inherit constants from superclass as class object methods , and allow the ability to override

so... 

package aaa;
use constant HELLO=> 'world';
use constant PUNCTUATION=> '!';
sub new { #std constructor here }

package bbb;
our @ISA= qw( aaa );
use constant HELLO=> 'universe';

package main;
my $a= aaa->new();
my $b= bbb->new();

print "\n Hello " . $a->HELLO . $a->PUNCTUATION ;
print "\n Hello " . $b->HELLO . $b->PUNCTUATION ;

[download]

will get you 

Hello world!
Hello universe!

[download]

but bbb->PUNCTUATION doesn't exist
