Well, it's compiling, and a valid way to do it, I guess. One detail,

kotlin
    window.customElements.define("fancy-button",  ::FancyButton,  object : ElementDefinitionOptions {
        override var extends: String? = "button"
    })

It's not really doing what I want. The JavaScript version take a reference of FancyButton. I think the define function will do new FancyButton(). The problem here, the compiled code is not working because it's trying to new (function () {return new FancyButton()})
