A modern programming language that makes developers happier.

kotlinlang

```
data class Foo private constructor (val a: Int, val b: Int)

fun Foo(a: Int, b: Int) = ...
```

it looks like that results in a conflicting override (and an accidental recursive call)

and if I change the method name, I still can’t access the private constructor from a top-level function

function and data class must be in the same file

they’re declared literally one after another in my code

so the best way is to use a `companion object` with `operator fun invoke`

that should work with a private constructor

How do you "override" a generated function?

I’m not sure that you can - I got a platform declaration clash when I tried

<https://kotlinlang.org/docs/reference/data-classes.html#data-classes> `If there are explicit implementations of equals(), hashCode() or toString() in the data class body or final implementations in a superclass, then these functions are not generated, and the existing implementations are used`

and `Deriving a data class from a type that already has a copy(...) function with a matching signature is deprecated in Kotlin 1.2 and will be prohibited in Kotlin 1.3.`

so you can't override `copy()` or `componentN()` :confused:

TIL wasn't aware that you can't override all methods that are generated

In this case it would help just to prohibit (make private) the `copy()` method.
I think it would make sense to give a finer grain control over generated methods.
