@myArray = qw(one two three four);

$self{'Next'} = \@myArray;
}
print "Element 0 is $self{'Next'}->[0]\n";

You can't specifiy the size of the array, it's dynamic. Just enter your data
into the array and it will change size accordi

No you don't:
foreach $i (0..@array) {
print "$array[$i]\n";
}

Uh, no. That looks like @foo[3], which works for some broken values
of "works". You want $foo[3], so to backtrace that, use ${$self->{Next}}[$n],

Well, in this case it was a cargo cultism. I understand why one may
want to do this, but that was not my intent when I was writing this; I
just grabbed an example constructor. I should have thought about
