Unused unary operator

Reports unary operators for number types on unused expressions.

Unary operators break previous expression if they are used without braces. As a result, mathematical expressions spanning multi lines can be misleading.

Example:

fun main() {
    val result = 1 + 2 * 3
                + 3              // <== note that '+ 3' doesn't belong to the 'result' variable, it is unused
    println("Result = $result")  // The result is '7' and not '10' as it might be expected
}
