alternative to void

[John Eisensmith]

I just saw ceylon and loved this language especialy the syntax immediately.
However i have a suggestion to improve the language in things i hated in many years developing java.
What should i do with void/Void as a return type? I never understood the answer to this question.
I will expect from a new language like ceylon something like this:

class AClass {
  self setMeIfYouCan(SomeTypeOf me) {
    //do something
    //and imlicitly return this
  }
}

AClass ac = new AClass().setMeIfYouCan(SomeTypeOf.INSTANCE);

instead of:

class AClass {
  void setMeIfYouCan(SomeTypeOf me) {
    //do something
    //and imlicitly return this
  }
}

AClass ac = new AClass();
ac.setMeIfYouCan(SomeTypeOf.INSTANCE);

Let me read your opinions about.

Bye

*Very* early versions of the Ceylon language spec had an operator
named ^. which was for chaining void methods. But then I decided it
kinda went against the grain of using immutable objects and named
arguments instead of the builder pattern.

Also, unlike in Java, where setters are methods, it does not help
chain several attribute assignments. I think that's perhaps the
biggest reason it wouldn't help much in Ceylon.

That's not to say I'm hostile to this feature, just that I don't
perceive it as very necessary.
