Rewrites for same class token

This is the usecase I'd like to make workable. I open this as a reference and will try to make a PR sooner or later.
````c#
public class MyClass{

private void MyMethod(){
var myOtherInstanceOfMyClass = RetrieveOtherInstance();
myOtherInstanceOfMyClass.MyOtherMethod();

myOtherInstanceOfMyClass = RetrieveOtherInstance(typeof(MyClass));
myOtherInstanceOfMyClass.MyOtherMethod();

MyClass myOtherAgain= new MyClass();
myOtherAgain.MyOtherMethod();
}

private void MyOtherMethod(){};

}

````

It seems doable as we simply need to rewrite `` and `Typeof(myclass)` and class naming, which is not rewritten when in the same class as of now.
