Subject: static:: and PHP 7 (from bug #70997)

Hi internals,

I'm looking for some feedback on a change with regard to static::, which
has been present throughout the 7 branch.

Have a look-see at https://bugs.php.net/bug.php?id=70997

<?php

class A {
    const TEST = false;
    public function test() {
        var_dump(static::TEST);
    }
}

class B extends A {
    const TEST = true;

    public function test() {
        A::test();
    }
}

$b = new B;
$b->test();

?>

In PHP 7 it dumps true, in PHP 5 false.

I'm looking for info on when, where, why it was introduced, and ultimately
some clarification of:
a) was this intentional
b) it is going to stay (i.e. "not a bug")
c) some more to go on so I can document the change clearly

If there is already a line in NEWS/UPGRADING or a commit you can point me
to, that would be amazing.

Whatever tangents this topic wanders off on, I'd like to eventually pull it
back to the bug report mentioned above with one eye on formulating the docs
changes (if it's really "not a bug").

Cheers,

A docs guy.
