Perhaps something like this would help, since it handles an arbitrarily large list of elements, all of which must be equal to your target value for the statement to return true.
#!/usr/bin/perl
use strict;
use warnings;
my $item1 = 'foo';
my $item2 = 'foo';
my @list = ($item1, $item2);
my $item3 = 'foo';
if ( scalar (grep { $_ eq $item3 } @list) == scalar @list) {
print "All are equal.\n";
}
Another way might be to synthesize a large string of $itemN = $item3 type code, and then eval it.
Hope this helped, -v.
Update:entire post rendered obsolete by blazar's excellent observation. I should've remembered DeMorgan's Law.

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).
