I shouldn't have to $fee = unserialize( serialize( $foo ) ) everytime i want
to get a copy of an object when the engine says it copys. That is FAR from
'clean'. A possible soultion for this to get around the speed vs functionality.
The engine could keep track of a copy and when and only when a member gets
change that is when it should make the copy of the member objects. So you get
the speed but it is transparent to the user.
