I've been doing PHP for very little time and I'm getting hooked

Hooray!

Finally a PHP will be a proper language, references and decent class support should mean serious developing. There's no word of polymorphism, which I hope is on the way (if it's a proper OO lang, it's essential) but PHP should run faster with referencing for functions. And exception support is a great addition, really helps error handling. As a learning C++ programmer, PHP is getting sweeter.
