Hi,

I'm trying to re-learn perl after a long hiatus. Trying to reverse the array contents without using the "reverse" function, just to see how much I understand things. Looks like I have totally forgotten everything.

Here is what I am trying:

use warnings;
use strict;
use diagnostics;

my @arr = ('a'..'z');
print "@arr\n";
foreach my $thing (@arr) {
    my $ele = pop @arr;
    my $stuff = unshift @arr, $ele;
    print "$ele ";
}
[download]

And here is the output:

C:\perlscripts>perl arrays.pl
a b c d e f g h i j k l m n o p q r s t u v w x y z
z y x w v u t s r q p o n m l k j i h g f e d c b a
C:\perlscripts>
[download]

What I fail to understand is, iterating the array using $thing variable but not using it at all in the loop still gives the expected result.

Tried printing out the $thing contents, by using print "[$thing]".

use warnings;
use strict;
use diagnostics;

my @arr = ('a'..'z');
print "@arr\n";
foreach my $thing (@arr) {
    print "[$thing]";
    my $ele = pop @arr;
    my $stuff = unshift @arr, $ele;
    print "$ele ";
}
[download]

Here's the output

C:\perlscripts>perl arrays.pl
a b c d e f g h i j k l m n o p q r s t u v w x y z
[a]z [a]y [a]x [a]w [a]v [a]u [a]t [a]s [a]r [a]q [a]p [a]o [a]n [a]m 
+[a]l [a]k [a]j [a]i [a]h [a]g [a]f [a]e [a]d [a]c [a]b [a]a
C:\perlscripts>

What am I missing? Something very basic and "duh" I guess..
