Hi @kaidesu , could you take a look at this? thanks thanks!

Currently, ++ is not working with Property

class Test {
    function constructor(score = 10) {
        this.score = score
    }
    function add() {
        this.score++
    }
    function show() {
        print(this.score)
    }
}

test = Test.new()
test.add()
test.add()
test.add()
test.show()
