I vote for (A). bind() and bindTo() seem messy to me. However, I
mostly vote for no implicit $this changes in closures (no
javascript-like behaviour), so (A+) approach would be much better than
(C) or (D). (0) case is not my choice, because I really would like to
see $this support in closures back.

Hi,
Maybe I don't exactly understand the need for closureProperty(); also,
I haven't read the rfc ;-)
My understanding would be that you can treat it as a callable object, like so:
$a = function($msg) { echo $this->id, ": ", $msg, " [ calls: ",
++$this->calls, "]";
}
$a->id = 123;
$a("hello wor

I don't quite follow: Why A+ if no direct method calling? What would be

one additional thing:
$a = static function () {}
should leave $this not bound (in case for some reason you don't want it
to be bound, e.g. to avoid keeping reference

I'm a little disappointed by the non-outcome of this debate. Very few
people have responded and most of them seem to agree proposal (A) should

You're talking about variable functions/methods. But that is not the
subject of discussion. Variable functions/methods are useful but
introduce mess. This is well-known and this feature exists in PHP for
a long time - so everybody should be condidered a
Hello.
Jelrik, I could easily show a real-world example where using $this in
closures could help. Consider Person class which has to verify that
email address is unique.
Suppose we have validation code in a single place and
filter_var_array() is used to check all the data:
class Person {

Hi!
If php-people really would like rebinding $this, I beleive this should
be done via method like Closure->bindTo() - to make the fact of
rebinding clear in the code.
However, there is a problem with rebinding $this - that was not
mentioned yet, I think.
This can be a problem, but since PHP

Hi!
That syntax made my eyes hurt, but I think really the problem is that

We can add method to Closure class to allow that. See Closure::bind and
