This code:

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


> false
> true

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

This has consequences which I think are counterintuitive:

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

The if clause evaluates as true and gives as output:
