new foo()->bar() should be read as: (new foo())->bar().

And using variable:

new $bar->y()->x should be read as: (new ($bar->y)())->x.

<?php

class foo {
public $x =3D 1;
}

class bar {
public $y =3D 'foo';
}

$bar =3D new bar;

var_dump(new $bar->y()->x); // 1

?>

I.e. just as it is nowdays.
