into the array and it will change size accordingly. If you want a scalar
reference to an array use this
@myArray = qw(one two three four);
$reference = \@myArray;
print @{$reference}[0];

Gee, just like pointers in C! :-)

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],

Given this is my definition for self in some new constructor:
sub new {
$self {
Next => @[Max_Level],
}
}
First, is this the proper way to have Next be a reference to an annonymous
array of size Max_Level?
More importantly, how do you reference the elements in the a
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
the choice to make "new" a function that could be called by both the
class and the object, b

PLEASE stop doing this.
I know there's a Very Popular Tutorial included with your

The thing is, I want to set the array reference later and not when the
object is being created.

Given that I am trying to define an object attribute which is an array of
references to other object of the same type, how do I define this in the
$self portion of my sub new constructor? This is what I have, will this
work? Next is meant to hold an array of pointers or references.
