Ah thanks :) But please bear with this nagging question: why doesn't \@letters point to the changed @letters inside the loop?
Update
Maybe I understand now...see modified code below:
use strict;
my $some_word = 'race';
my @letters = split //, $some_word;
my (@array1, @array2);
# Added this to show that the same $letter_ref is pushed into @array2
my $letters_ref = \@letters;
for (1..@letters) {
my @new = @letters;
push (@array1, \@new);
push (@array2, $letters_ref);
my $myshift = shift @letters;
push(@letters, $myshift);
}
Update 2
My above reasoning was wrong. See my reply to neniro at Re^2: Puzzled by array

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
