Should A. be preferred over B. for some reason? A. `open fun x() = Unit` B. `open fun x() { }`

Should A. be preferred over B. for some reason?
A. open fun x() = Unit
B. open fun x() { }

[Fleshgrinder]

I guess this is a question of taste. I prefer A. because B. looks like somebody forgot to implement things, unless they do:

open fun x() {
    // Intentionally left blank.
}

If a function returns Unit, the return type should be omitted:

```fun foo() { // ": Unit" is omitted here

}```

(more of a #codingconventions question than #compiler; kotlinc produces the same output either way)

[Fleshgrinder]

Agree regarding #codingconventions but the quote does not address the question, because in both forms the return type is omitted. 😉
