Hello, I have a problem. How to cast type <T> to <Base<T>> ?

open class C<T:C<T>>{
    fun <R> foo(a:R){
        a as T // looks not works...
    }
}

What is the definition of Base<T> ?

[tseisel]

Casting an R to T is completely unsafe, as there is no defined relationship between T and R.

I would have worked with

open class C<T : C<T>> {
    fun foo(a: T) {
        // a is already a T
    }
}
