variant property wrapper behaves like an array, but fails for splice or delete

I can not change the contents of an array using splice or delete.

See following example or attached file:

import QtQuick 1.0

Item {
width: 100; height: 100

property variant array: ["0", "1", "2"]

Component.onCompleted:

{ //var array = ["0", "1", "2"] // Outputs ["0","1","2"] console.log(JSON.stringify(array)) var ret = array.splice(1, 1); // Should be ["0","2"] ["1"] but is ["0","1","2"] ["1"] console.log(JSON.stringify(array), JSON.stringify(ret)) delete array[1]; // Should be ["0",null] but is ["0","1","2"] console.log(JSON.stringify(array)) }

}
