This should be easy to fix/upgrade, since we can already 
instantiate a class:

import std;

class foo{
     void hi(string who){ writeln("Hi ", who); }
}

void main(){
     auto f = new foo();
     f.hi("There!");
     foo f2;
     with(f2 = new foo()){
         hi("Again!");
     }
}

Hi There!
Hi Again!

One thing missing is Declaration. (I wonder why this is not 
already implemented!?).
