What's MI?

Btw, I can't see why you can't initialize your own object from constructor. One of the definitions I found about this is: "A constructor is responsible for preparing the object for action, and in particular establishing initial values for all its data, i.e. its data members. Although it plays a special role, the constructor is just another member function, and in particular can be passed information via its argument list that can be used to initialise it" (here).
