I agree.
To make it simple you can do like this:

template copycast (T : T[])
{
  T[] copycast (X) (X[] array) 
  {
    T[] retVal = new T[array.length];
    foreach (int i, X elem; array)
    {
      retVal[i] = cast(T) elem;
    }
    return retVal;
  }
}
 
int main()
{
  int[] a = new int[10];
  long[] al = copycast!(long[]) (a);
 
  interface I {  }
  class A : I {  }
  A[] array = new A[10];
  I[] dest = copycast!(I[]) (array);
 
  return 0;
}
