For what it is worth, I have extended my template class with a clear_var()
function (below). After parsing each loop, I call clear_var() with the
varname(s) that may be blank. For instance:

while($db->next_record()) {
	$tpl->set_var("some_var", $db->f("some_var"));
	if($db->f("optional_var")) $tpl->set_var("optional_var",
$db->f("optional_var"));
	$tpl->parse("some_block", "some_loop", true);
	$tpl->clear_var("optional_var");
}

I really appreciate it on large blocks with several optional variables.
Here's my function:

	/* public: clear_var(array $varnames)
	 * varnames: array of variable names to be cleared
	 *
	 * public: clear_var(string $varname)
	 * varname: name of a variable that is to be cleared
	 */
	function clear_var($varname) {
		if(is_array($varname)) {
			while(list(,$value) = each($varname)) {
				$this->set_var($value, "");
			}
		} else {
			$this->set_var($varname, "");
		}
	}
