While I really prefer to use tools like this for deployment, I understand that not everyone wants to mess with standalone programs and configuration files. I've been asked before about Cake-specific deployment techniques, so I figure the easiest way is to see about adding a task to the Cake console.

His idea consists of two new commands - "cake deploy config" and "cake deploy" to make it simple to set up and directly deploy applications without having to go to outside software.

As a language construct within PHP it would be very easy to do the same, but easier to learn and to use. Beside some keyword issues (the RFC uses "use" as keyword, but this will of course conflict with namespaces) I'm wondering what this will have an impact on reflection - the RFC stays unclear about this.

A trait is a free-floating chink of functionality that, instead of being confined to a class (or file) that has to be called on to use it, exists where the developer can use it from anywhere at any time. This helps solve some of the issues with single inheritance in PHP.
