Currently Kotlin's data classes have copy() which isn't smart 🙂

data class Value(val v: Int)

val v1 = Value(1)
val v2 = v1.copy(v = 1)
println(v1 === v2) // prints 'false'

I wonder if it will be ever possible to have above code to print true? To reduce unneeded allocations when data class is immutable?
Or will this be something not in core language, but in stdlib?
