It won't get called unless you call it ;-)

I was kind of assuming that the Template code calls the subroutine at some point! After all, it gets passed the reference...

In the example code, get_user_projects doesn't seem to be explicitly called. 

#!/usr/bin/perl
use strict;
use warnings;
use Template;
use CGI;

$| = 1;
print "Content-type: text/html\n\n";

my $file = 'userinfo.html';
my $vars = {
    'version'  => 3.14,
    'days'     => [ qw( mon tue wed thu fri sat sun ) ],
    'worklist' => \&get_user_projects,
    'cgi'      => CGI->new(),
    'me'       => {
        'id'     => 'abw',
        'name'   => 'Andy Wardley',
    },
};

sub get_user_projects {
    my $user = shift;
    my @projects = ...   # do something to retrieve data
    return \@projects;
}

my $template = Template->new({
    INCLUDE_PATH => '/home/abw/websrc/src:/home/abw/websrc/lib',
    PRE_PROCESS  => 'config',
});

$template->process($file, $vars)
    || die $template->error();
