pointless - I would even go as far as disallowing passing $this by references to a function - where the reference has to be ignored again,

This would be needed to have something like function setfoo(&$obj) { $obj->foo = 42; } [...] $other->setfoo($this); in a way which also works for PHP4. a) I know that you now are going to bash me for mentioning PHP4 b) No, I don't think this is very common or elegant But disallowing it might break existing code, no? - Chris
