How to use function overload for list of data type?

e.g:

fun fun1(list: List<DataA>)

fun fun1(list: List<DataB>)

The current condition declaration was clashed. any workaround?

1. I've tried to use typealiases but it still clashed. e.g: typealias ListDataA = List<DataA>
2. Using extensions function, still clashed. e.g: ListDataA.fun1()

The problem is that both function are compiled to the same function in java, which is fun1(list: List). One think you could do is adding @JvmName to convince the compiler to use different name while compiling, like this:

@JvmName("fun1DataA")
fun fun1(list: List<DataA>)

fun fun1(list: List<DataB>)

If that doesn't work ^, then you could do fun fun1(list: List<Any>) and then check if the list's contents are DataA or DataB. That way you have one function.

Currently, I'm checking the list of contents is DataA or DataB. But here's my actual usecase:

typealias ListMovieEntity = List<MovieEntity>
typealias ListMovieResponse = List<MovieResponse>

class MovieEntityMapper {

    companion object {
        fun <S : Any, D : Any> from(movies: ListMovie<S>): List<D> = movies.map {
            with(it) {
                when (this) {
                    is MovieEntity -> Movie(id)

                    is MovieResponse -> MovieEntity(id)

                    else -> TODO()
                } as D
            }
        }
    }
}

actually I've two generic class. source & destination. is it the right way to do this?
