Aha!  Found it!

Yapcom, the CGI::App-based application to handle registration and 
workshops for YAP conferences!

Here is the relevant piece of code.  Personally, I think this is a VERY 
tasty hack.  It lets page designers plug parameters back into the 
templating system for use elsewhere.  Very cool.

sub _server_page {
    my $self = shift;
    my ($page) = @_;
    my $q = $self->query;

    # we allow tags like this in our templates that will define values
    # to be set as parameters
    # <TMPL_VALUE NAME="name" VALUE="value">
    my %h;
    my $filter = sub {
       my $text_ref = shift;
       while ($$text_ref =~ 
s/<\s*TMPL_VALUE\s+NAME="([^"]*)"\s+VALUE="([^"]*)"\s*>//) {
          $h{$1} = $2;
       }
    };

    my $t = $self->load_tmpl(
        "$page.tmpl",
        die_on_bad_params => 0,
        filter => $filter,
        associate => $q,
        path => $templates_dir,
    );

    $t->param(%h);
    $t->param(VERSION => $YAPC::Organizer::VERSION);

    return $t;
}
