Nested data templates

A field can use another data template as its type. This groups related data.

data Position {
    var x: int
    var z: int

    constructor(x: int, z: int) {
        this.x = x
        this.z = z
    }
}

data Checkpoint {
    var name: string
    var position: Position

    constructor(name: string, position: Position) {
        this.name = name
        this.position = position
    }
}

func main() {
    var checkpoint = Checkpoint("Spawn", Position(10, 20))
    print(checkpoint.position.x)
}

Checkpoint combines a name and position. checkpoint.position.x accesses position and then x.

Constructors receive typed field values. Declare fields with var name: Type. Create nested objects through ordinary constructor calls.

Name structures that you reuse. Anonymous structures use data { ... } as a type with the same field declaration rules.
