I don't see why it would process the original file a second time

sub process {
    my ($self, $hash, $args) = @_;

    my $fn = $self->SUPER::process($hash, $args);
    my $tpl = Petal->new($fn);
    return $tpl->process($hash);
}

the first ->process just finds the name of the included file, ->new loads it
and the second ->process processes the included file.
