Subject: Re: [PHP-DEV] planning future BC Breaks  - was Re: [PHP-DEV]
	fatal static call in php 6.0?

Yeah I heard, but it doesn't mean it'll become a part of the language 
(doesn't mean that it would not, but as usual, no discussion ;).

What Alan suggested is already a part of the language, bares no 
additional overhead (both CPU cycles and brain cycles), and also 
(least important point) is very easy to implement.
