Property accessors

In Cola you have access to elements of array via dot accessor:

console.log([0..10].5) // 5

From Dart was taken cascade accessor:

document.querySelector("#myelement").style
..fontSize = "16px"
..color    =  "black"

but ColaScript have some modification:

document.querySelector("#myelement")
..style:
    ..fontSize = "16px"
    ..color    =  "black";
..innerHTML = "Hello World!"

and in ColaScript you can define a function in cascade:

FileReader reader = new FileReader()..onload(loadEvent) {...}

From CoffeeScript was taken prototype accessor:

Array::forEach.call([0..9], (_) => console.log(_))

String String::replaceAll(a, b) {
    String res = this

    while res.indexOf(a) != -1 {
        res = res.replace(a, b)
    }

    return res
}

Also from CoffeeScript was taken conditional accessor:

console.log(someObj?.test()); // undefined

var someObj = {
    test: () => "test called"
};

console.log(someObj?.test()) // "test called"
