Is it possible to overload C++11 new operator to create smart pointer instead?

I want to use C++11 smart pointers always, with traditional pointer syntax (which a little similar to Java syntax) , because I don't want to worry about memory management , I think it's good idea to overload new operator with custom one, in other words

Instead of create new object dynamically like this :

    obj *o = new obj();

which create traditional pointer to obj, I want to make it create smart pointer , like this

    obj *o = new obj(); // o will be deleted automatically

How do I make something like this ?

Note : I don't want to replace the original new operator ,I just want to overload my own class one.

Thanks .
