Well, if this feature is going to be accept, we could to decide what syntax
to use.
I have created another patch which is the bracketed version of this
presented here.
<?php
class foo {
public $x = 1;
}
class bar {
public $y = 'foo';
}
$x = 'bar';
$bar = new bar;
var_dump((new bar)->y); // foo
var_dump((new $x)->y); // foo
var_dump((new $bar->y)->x); // 1
?>
Thus we do not have the readability issues, as pointed by Johannes.
