Bug description:Closures have invalid context
Description:
------------
It doesn't make sense that closures declared inside methods are run with
global context instead of the same context as the method. This is
incredibly annoying as it there are no way to reference private/protected
functions in closures. It's not possible to acquire a reference to the
private/protected functions and pass them to the closure either so you're
locked out from a developers perspective.
See test script.
The fix should be simple. Just inherit the access-context when closures are
declared...
Test script:
---------------
class Foo {
private function bar($a, $b) {
return $a + $b;
}
public function baz($c) {
$biz_fn = function($c) {
return Foo::bar(5, 4) - $c;
};
return $biz_fn($c);
}
}
$foo = new Foo();
echo $foo->baz(3);
Expected result:
----------------
"6"
Actual result:
--------------
Fatal error: Call to private method Foo::bar() from context '' in..
