If I have this code

fun test(a: Pair<Int, String>, b: Pair<Int, String>): Boolean {
    return a.first == b.first
            && a.second == b.second
}

and use extract variable refactoring to get:

fun test(a: Pair<Int, String>, b: Pair<Int, String>): Boolean {
    val result = (a.first == b.first
            && a.second == b.second)
    return result
}

you can see IDE added parentheses there. Aren’t those unnecessary? IDE doesn’t offer an intention to get rid of them. But if I do, it compiles and runs the same.

I have this intention if the whole expression is in one line

Maybe it’s because sometimes the parens are need for multiple lines, like with

(a
  + b
  + c)

But I’m thinking it doesn’t matter in this case?
