Feature proposal : php.ini option to disable access control and interfaces

Hi, Is it possible or planned to have a php.ini option in order to disable interfaces and access control ? something like assert.active for assertions. What I mean is something like a option "access_control.active". If it is disabled then PHP do not check private/public/protected access, do not load interfaces definitions with __autoload and do not use them. Could this speed up some script which have proven to be stable and correctly designed ? it should avoid loading some files (interface definitions) and avoid some checks (access controls). Am I right to think it may help performance ? and is this feature possible ? (probably not for 5.0 as we are in RC, but somewhere in future) Sincerely, -- Eric Daspet
