I was today year old when I learned you can `override fun toString()` on value classes and it works!
```@JvmInline
value class LongPos(val value: Long) {
    override fun toString() = "$row,$col"
}

fun longPos(row: Int, col: Int) = LongPos((row.toLong() shl 32) or (col.toLong() and 0xFFFF_FFFFL))
val LongPos.row get() = value.shr(32).toInt()
val LongPos.col get() = (value and 0xFFFF_FFFFL).toInt()```
This will make my debugging somewhat easier :slightly_smiling_face:

Question: why not also add
```constructor(row: Int, col: Int)): this((row.toLong() shl 32) or (col.toLong() and 0xFFFF_FFFFL))```

of course it's also possible, I think I'll also have other implementations. like:
```typealias PairPos = Pair&lt;Int, Int&gt;
fun PairPos.row get() = first
fun PairPos.row get() = second```
And in my code I'll be just using
```typealias Pos = PairPos // or = LongPos```
but maybe it's overcomplication, I'll see :slightly_smiling_face:

Yeah, I normally use a `data class Point(val x: Int, val y: Int)` in my AoC code. Pretty sure your LongPos is more efficient, but I normally do not care so much about efficiency of my AoC code (as long as it finishes within some seconds), and instead care more about code prettiness (of course also very subjective).
