Does this become a property automatically, or is it still a method
call? To that end, some examples of *using* a data class, not just
defining one, would be helpful.
If it remains a normal method, why put it in this example at all? Makes
Nothing is done with total_cost, it's still a method. It's meant to show
that you can use methods in a Data Class. Maybe I should add a method
that has a parameter, or at least explain why that method is present in
the example.
I'm not sure how I'd write an example showing you can you do everything
you can with an undecorated class. I think some text explanation would
be better.
