Is there an idiom for collection.map { it.unsafeCast<SomeExternalInterface> } which is undestood by the compiler and transpiled efficiently? It is something that comes up from time to time when interacting with js libs and last time I checked the resulting code was a for loop instead of a no-op

inline fun <T, R: T> List<T>.unsafeMap(): List<R> {
    unsafeCast<List<R>>()
}
