Subject: Re: [PHP-DEV] fatal static call in php 6.0?
From: helly@php.net (Marcus Boerger)

Hello Andi,

  passing $this to a static function is a different set of problems calling
trouble on another front. If you pass $this to a static function you sooner
or later pass it as $this and sooner or later you call back into the object
scope from that $this. Now the trouble is that suddenly we have two $this.
The obejct $this which is a pseudo variable controlled by the engine and
which cannot be overwritten and $this in the local symbol table. The one
that can be changed and even unset. I am quite sure the engine is not
designed to take care for this situations in all places. That said sooner
or later the same people complaining now will shout at us: hey you stuff
sucks - fix it.
