good point, you could do:

arrayOf(1, 2, 3)
            .map { Pair(map[it]!!, it) }
            .filter { it.first != null }
            .map { plusOne(it.first) }

Even though you get a warning on the filter, claiming it will always be true. This is an interesting case though, I have no clue whats best to do here!
