True. But one still has to keep in mind that the constructor is not
constructing the object, but initializing it.

You would have to take extra measures to prevent re-initializing an
already initialized object. Your constructor would need to detect what
type of initialization is required (freshly created by `new`, cloned or
unserialized). While certainly possible, this would be cumbersome.
Different magic initializers are clearly the better way to go.

__wakeup() is an initializer, just like __construct() and __clone(). And
__sleep() is still not a destructor -- see my earlier post.

I think we do agree that __sleep() is not a destructor. And maybe we can
agree that __construct(), __clone() and __wakeup() all perform
initialization tasks and thus could be all called "initializers".
