If you want to do this you need to define a function/method that
returns an instance for you. So you can say
class bob {
public static function getInstance() {
return new bob();
}
public function foo() {
}
}
bob::getInstance()->foo();
I've seen on the internals list where core dev's said it doesn't make
sense to chain off a constructor. If you want this behavior then you
need to do it off a method. This is just how things work is all it
boils down to.
