hi,,,currently im reading the "Intermediate Perl" book. im being bugged by the anonymous data structures. a part of the book it says that anonymous data structures are structures that do not have explicit names. so i understand (correct me if im wrong) that this "names" that is being point out, would be like ($my_ref, $var, $_, etc...) that is implicitly created by perl.

as we could see on the example below: 

for (@_) {
   print;
   $_ = undef;
}

[download]

we all knew that the implicit variable here is $_ that is being printed out. so in connection with creating anonymous data structures below: 

my $ref = ["my","list"];

[download]

what would be that implicit name (variable) that was created? and how can i access it?

if i was wrong of pointing out that this "name" is a variable rather was a memory address, then it means:

EXPLICIT NAME: $var

IMPLICIT NAME (memory address): 0x25512

VALUE: perl

am i right? that there are two ways to access a value, by using the explicit name, and through an implicit name.

thanks in advance... keep deep and dark!
