 New Comment:

Actually it wouldn't work because $sfoo is private. https://3v4l.org/iLVpZ

A::$sfoo demonstrates that the code can access the property member, while self::$sfoo would
demonstrate that the code is running from "within" the A class. Both mean the same thing.
But the second callback already shows the "within the A class" aspect by using $this, so I
think having A::$sfoo being clearer about accessing members is good.

Does that make sense? Agree or disagree?

Description:
------------
---
From manual page: http://www.php.net/closure.bind
---
Example 1 contains a following code:

<?php
$cl1 = static function() {
    return A::$sfoo;
};
?>

My suggestion:
<?php
$cl1 = static function() {
    return self::$sfoo;
};
?>
This example show why use bind(), but A:: works without bind().
