While trying to add a "native" property to Menu, I came across an error:

import QtQuick
import QtQuick.Controls.Material

ApplicationWindow {
    id: window
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Menu {
        id: menu
        native: true

        Action { text: "Cut" }
        Action { text: "Copy" }
        Action { text: "Paste" }
    }

    TapHandler {
        onTapped: menu.open()
    }
}

QQmlApplicationEngine failed to load componentqrc:/main.qml:13:9: Expected token `}'

After reading QTBUG-16062 and consequently https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Lexical_grammar#keywords, I see that it is a reserved word.

However, that bug report was closed without any documentation added, and now we simply have this cryptic error message. We should add the list of reserved words to the docs and produce a more useful error message (which could link to the documentation).
