What Tommy just said. This the Wrong Way™ to do it. That said, I do exactly this sometimes with Template by using named blocks. Here's a runnable example- 

use warnings;
use strict;
use Template;
use CGI qw( header );

print header();

my $tt2 = Template->new( TRIM => 1 );

my @actions = qw( foo bar );
my @titles = ( "O HAI", "O NOES", "KTHXBAI" );

$tt2->process(\*DATA,
              { title => $titles[rand@titles],
                my_action => $actions[rand @actions],
            })
    or warn $tt2->error;

__DATA__
[%~BLOCK foo %]
This is my foo. There are many foos like it but this one is mine.
[%~END %]

[%~BLOCK bar %]
This is my barbaz. This is my qux. This is for coding, this is for... 
+uh...
[%~END %]

[%~# TEMPLATE ----------%]
<html lang="en">
 <head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /
+>
  <title>[% title | html %]</title>
</head>
<body>

 <header>
  <h1>[% title | html %]</h1>
 </header>

 <article>
    [% PROCESS $my_action %]
   <aside>Action: [% my_action | html %]</aside>
 </article>
