Ownership you can read.

As safe as Rust. As fast as C. More readable than both.

Native code, no garbage collector, no lifetime annotations. Every call shows who owns the data. KonLang 1.0.0 is Stable — the compiler now builds itself.

struct Player {
    name: String
    health: i32
}

// view reads, edit changes, take hands over.
func describe(player: view Player) {
    print(player.name)
    print(player.health)
}

func heal(player: edit Player, amount: i32) {
    player.health += amount
}

func main(): i32 {
    var hero = Player { name: String("An"), health: 80 }
    heal(edit hero, 20)
    describe(hero)
    return 0
}
