I stayed so close to the code posted by @Pavlo Liapota it is straight-up plagiarism, so no need to post it. 🙂

Today's timings (first/best of 25 in ms): JVM 256/19, JS 316/130, native 649/393

I did discover something useful today - you can have more than one operator fun get and set implementation in a single class.

So for today, I wrapped an val grid: Array<Array<Soil>> in a class, and defined the following methods:

operator fun get(pos: Position) = grid[pos.x][pos.y]

operator fun get(x: Int, y: Int) = grid[x][y]

operator fun set(x: Int, y: Int, type: Soil) {
    grid[x][y] = type
}

operator fun set(pos: Position, type: Soil) {
    grid[pos.x][pos.y] = type
}

so I can use both world[x, y] and world[pos] at my convenience (and do some bounds checking not shown above)
