Concatenate - string operator on object property

[mruz]

Concatenate the string not working properly:

class Tag
{
    protected static _documentTitle = null;

    public static function appendTitle(string title)
    {
        let self::_documentTitle .= title;
    }

It overwrites the _documentTitle.

Issue related to #119.

@mruz Can you try with latest zephir version and maybe create test for this bug?

this is not implemented. now i am working on this.

How about protected property:

class Test
{
    protected a = "" { set };
    protected output = "" { get };

    public function append()
    {
        let this->output .= this->a;
    }

$t = new Test();
$t->setA('a');
$t->append();
$t->setA('b');
$t->append();
echo $t->getOutput(); //only `b` now
