Re: [PHP-DEV] getInstance and new self()

[Andi Gutmans]

self:: is always evaluated at compile-time and refers to the class it is 
defined in and not the concrete object/class.

Expected output would be "object(foo)", so I guess either "self" should
not be evaluated at compile time or this should be disallowed. I'd
prefer the first:)
