It's something I noticed, too. Consider this:
class A {
function a() { return $this::b(); }
function b() { return 1; }
}
class B extends A {
function b() { return 2; }
}
If I call
$b = new B();
echo $b->a();
No matter what combination of this, self, parent, ... - I could never get
B's property. I was led to believe that this is actually normal for OO
designs (is it? If so, ignore me). But it would be awesome if self or $this
(ONLY one of them, if they currently perform the same function) actually
referred to the top class - ie. B::b() in this case. Is this what this
suggestion would suggest?
Thanks,
Jevon
