What is the lowest common ancestor of Array<Int> and Array<in Int>? In my opinion it should be Array<in Int>. But kotlin compiler thinks it's Array<out Int?>. I agree that Array<out Int?> is supertype of both Array<Int> and Array<in Int>, but it's not the lowest. What do you think?

I agree it should be Array<in Int>, so in this case the type inference seems to be not inferring the most specific supertype.
