Why won't this compile?

open class Queue<Element>(protected var backingList: MutableList<Element> = mutableListOf()) {
    fun listValue():List<Element> = List(*(backingList.toTypedArray().copyOf()))
}

Error:

Error:(44, 56) Kotlin: Cannot use 'Element' as reified type parameter. Use a class instead.

@benleggiero See definition of toTypedArray. Element must be reified https://kotlinlang.org/docs/reference/inline-functions.html

@elizarov but

reified

is only applicable to local generic types for inline functions, and I don't see any way to make that happen

true. There does not seem to be a way to use it here. In this particular case,

backingList.toList()

would do what you are trying to do.

Thanks!
