If you want to check the value, you'll need to do something like this:

Code:
#! /usr/bin/perl -w

use Data::Dumper;

my @array = ("apple","ball","cat","dog","elephant");

$_ = pop(@array);

if(m/elephant/) {
unshift(@array, $_);
}

print Dumper(@array);

Notice that the m// is implicitly working on the $_ variable.

template::plugin::dumper

Template::Plugin::Dumper(3)				User Contributed Perl Documentation			       Template::Plugin::Dumper(3)

NAME

       Template::Plugin::Dumper - Plugin interface to Data::Dumper

SYNOPSIS

	   [% USE Dumper %]

	   [% Dumper.dump(variable) %]
	   [% Dumper.dump_html(variable) %]

DESCRIPTION

       This is a very simple Template Toolkit Plugin Interface to the Data::Dumper module.  A "Dumper" object will be instantiated via the
       following directive:

	   [% USE Dumper %]

       As a standard plugin, you can also specify its name in lower case:

	   [% USE dumper %]

       The "Data::Dumper" "Pad", "Indent" and "Varname" options are supported as constructor arguments to affect the output generated.	See
       Data::Dumper for further details.

	   [% USE dumper(Indent=0, Pad="<br>") %]

       These options can also be specified in lower case.

	   [% USE dumper(indent=0, pad="<br>") %]

METHODS

       There are two methods supported by the "Dumper" object.	Each will output into the template the contents of the variables passed to the
       object method.

   dump()
       Generates a raw text dump of the data structure(s) passed

	   [% USE Dumper %]
	   [% Dumper.dump(myvar) %]
	   [% Dumper.dump(myvar, yourvar) %]

   dump_html()
       Generates a dump of the data structures, as per dump(), but with the characters <, > and & converted to their equivalent HTML entities and
       newlines converted to <br>.

	   [% USE Dumper %]
	   [% Dumper.dump_html(myvar) %]
