Example:

  data class My(val first: String, val second: Int, val third: Boolean)

  fun foo(list: List<My>) {
      list.forEach { my ->
          println(my.second)
          println(my.third)
      }
  }

The quick-fix destructures the declaration and introduces new variables with names from the corresponding class:

  data class My(val first: String, val second: Int, val third: Boolean)

  fun foo(list: List<My>) {
      list.forEach { (_, second, third) ->
          println(second)
          println(third)
      }
  }
