Something similar to the Linux Kernel features approach. I've never seen this approach used in PHP development process, I've always been seeing the "feature freeze -> support for a long time -> deprecate -> remove in the next major version" approach. Marking a particular language feature as experimental would allow you to drop it or to change it without notice even in a patchlevel release (5.3.1), resulting in a way quicker and more dynamic development process. The benefits? Nobody (but me...) would install an unstable version of PHP in a production environment, but probably some people would taste an experimental feature included in a stable version. Just my 2 cents. Regards, -- Giovanni Giacobbi
