Ownership you can read.

Kon compiles to native code with no garbage collector. Every call shows whether data is read, changed or handed over, and there are no lifetimes to learn.

The goal is a language as safe as Rust, as fast as C and easier to read than both. It is a goal, not yet a result: Kon is still being built.

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
}
