'when' that can be simplified by introducing an argument

Reports a when expression that can be simplified by introducing a subject argument.

Example:

fun test(obj: Any): String {
    return when {
        obj is String -> "string"
        obj is Int -> "int"
        else -> "unknown"
    }
}

The quick fix introduces a subject argument:

fun test(obj: Any): String {
    return when (obj) {
        is String -> "string"
        is Int -> "int"
        else -> "unknown"
    }
}
