Subject: RE: [PHP-DEV] Syntactical change to Scalar Type Hints RFC
From: zeev@zend.com (Zeev Suraski)

FWIW, while I think strict types - stricter than even strict languages -
don't belong in PHP, this syntax is clearly a step up from declare(), which
was definitely not intended for this purpose.
