In case you haven’t heard yet (pretty much impossible, isn’t it): PHP5.4 has been released.
In a previous post I already pointed out the possibilities for traits – although I am not quite sure yet how it could benefit current cake projects.
This article describes some more news and features regarding this new release.
I certainly won’t use any of the "syntactic sugar" like short array syntax anytime soon. It would just break with the current way of writing arrays – and then one would end up with two different syntaxes in the same app or even class.
But some of new features (besides the traits) sure look promising!
What will you be using? Or is there – especially regarding cake – no real use for any of those new features?
