Destructuring declarations with too many entries are hard to read and understand. To increase readability they should be refactored to reduce the number of entries or avoid using a destructuring declaration.

Noncompliant Code

data class TooManyElements(val a: Int, val b: Int, val c: Int, val d: Int)
val (a, b, c, d) = TooManyElements(1, 2, 3, 4)

Compliant Code

data class FewerElements(val a: Int, val b: Int, val c: Int)
val (a, b, c) = TooManyElements(1, 2, 3)
