I disagree with that. If your code base is small enough, a few redundant lines (idioms) don't matter. To bring up k again, the language has already done about the maximum amount of abstraction possible. There's really no room for the programmer to make reusable abstractions; any useful ones have already been made. That allows you to do very useful things in very small amounts of code.
