    I'm binding some properties to Loader.item.

    Loader {
        id: loader
        sourceComponent: comp
        Binding {
            target: loader.item
            property: "prop"
            value: 1
            when: loader.status === Loader.Ready
        }
    }
    

    If loader.item doesn't has prop, then the Binding should do nothing, otherwise, pass the value to loader.item. Note that you can't do like

    Binding {
            ...
            when: loader.status === Loader.Ready && loader.item.prop !== undefined
    }
    

    Because you can't assume that the value of loader.item.prop is not undefined.
