Subject: Re: [PHP-DEV] planning future BC Breaks  - was Re:
	[PHP-DEV]	fatal static call in php 6.0?
From: zeev@zend.com (Zeev Suraski)

I read it as if it was declare() ;)

I agree with Pierre that the best way to handle BC break is not to 
introduce it, but since that's not always 100% possible, this may 
make sense.  Of course, it'll only work with stuff that is 
syntax-compliant with the currently running PHP version, but that 
covers most BC breakage.
