Any way to override a data class' componentN functions? This for instance throws error "Conflicting overloads: public final operator fun component1(): String defined in Foo":

data class Foo(val bar: Int) {
    operator fun component1() = bar.toString()
}

No — see https://kotlinlang.org/docs/data-classes.html

• Providing explicit implementations for the componentN() and copy() functions is not allowed.

But that restriction only applies to data classes. You can define your own componentN functions for any other class.

If it's just a single-property class you can use a value class and define a component1()
