scss mixins - Sass: applying a shared class to every selector in a content block

Question

If I have a block of styles in Sass like this:

.class1 {

   .class2 {

   }

   .class3 {

       .class4 {

       }
   }
}

How can I use Sass to transform the above into the form below? I would like to avoid repeatedly typing .class or #{$i}.

.class1.class {

   .class2.class {

   }

   .class3.class {

       .class4.class {

       }
   }
}
