@optics generates bad code for data class with generic named 'S'

[ajrouvoet]

With arrow 1.2.3 on Kotlin 1.9.23 and ksp 1.0.19 the following declaration causes bad code to be generated:

@optics
data class Box<S>(val s: S) {
    companion object
}

producing:

public inline fun <S,S> arrow.optics.Iso<S, Box<S>>.s(): arrow.optics.Lens<S, S> = this + Box.s()
public inline fun <S,S> arrow.optics.Lens<S, Box<S>>.s(): arrow.optics.Lens<S, S> = this + Box.s()
public inline fun <S,S> arrow.optics.Optional<S, Box<S>>.s(): arrow.optics.Optional<S, S> = this + Box.s()
public inline fun <S,S> arrow.optics.Prism<S, Box<S>>.s(): arrow.optics.Optional<S, S> = this + Box.s()
public inline fun <S,S> arrow.optics.Getter<S, Box<S>>.s(): arrow.optics.Getter<S, S> = this + Box.s()
public inline fun <S,S> arrow.optics.Setter<S, Box<S>>.s(): arrow.optics.Setter<S, S> = this + Box.s()
public inline fun <S,S> arrow.optics.Traversal<S, Box<S>>.s(): arrow.optics.Traversal<S, S> = this + Box.s()
public inline fun <S,S> arrow.optics.Fold<S, Box<S>>.s(): arrow.optics.Fold<S, S> = this + Box.s()
public inline fun <S,S> arrow.optics.Every<S, Box<S>>.s(): arrow.optics.Every<S, S> = this + Box.s()

which naturally fails to compile due to the duplicate declarations of the type variable S.
