CentOS - Oct 2011 - L9 - what is a value

This code:

var('i') = string;
boolean($i); '<br>';
var('i') = array;
boolean($i); '<br>';

gives:

 > false
 > true

So an empty array gives "true" but an empty string "false".
This is different from L8. Is this intentional? If so, why?

Sorry, wrong list! This is Lasso code.

This has consequences which I think are counterintuitive:

var('i') = array(1);
if($i -> find('whatever'));
i	'true'; '<br>';
	$i -> find('whatever'); '<br>';
/if;

The if clause evaluates as true and gives as output:
	true
	array()
