PROPOSAL: Return 'this'

>   if (person.isMarried()) {
>     append("(married)");

class Some{

   void method2(Object..)

   void test(Other other){
      other do {
        method1();
        method2(method2()); // unclear
        method2(Object..);
        method3();
      };
   }
}

class Some{

   void method2(Object..)

   void test(Other other){
      other do {
        .method1();
        .method2(method2()); // clear
        .method2(Object..);
        .method3();
      };
   }
}

We should focus to not create to many interactions, or make people to
wander about 'what's this code do?'
Will that be clear for someone who see method2 in same screen?
Is increasing kinds of blocks good way?
