Bug description:inconsistent error-handling for $this
Description:
------------
$this is not generally allowed outside an object context, but sometimes it
is.
I discovered this while trying to write a cheeky little base-class that
would
allow you to decorate objects with new methods, at run-time.
I would have gotten away with it, too - and I still could of course, only I
would
have to break from the convention of $this, and naming the context-object
something else, which kind of sucks.
Test script:
---------------
<?php
$foo = function($this)
{
var_dump($this); // this will work!
};
$foo('bar');
// now an object:
class Test
{
public $foo = 'bar';
}
$test = new Test;
// and another closure:
$ouch = function($this)
{
var_dump($this->bar); // this will blow up
};
$ouch($test);
Expected result:
----------------
The two examples should either fail consistently, or succeed consistently.
>From my point of view, why should I not be allowed to have a local variable
named
$this if I wanted to? There's nothing special or magical about this
variable,
besides the fact that it gets automatically assigned on call.
Actual result:
--------------
The second example fails.
