JavaScript function definitions cannot be changed at runtime

If you define a function in QML, it would be important for the Qt Creator / QML debugging integration to be able to redefine the function contents during runtime. So if you have

function foo() {
console.log("blah");
}

it should be possible to rewrite this to

function foo() {
console.log("foo"); // or anything else
}

It's not so important to change the function signature, but if that comes for free, that would be a great addition as well.

It's not important to have this functionality publicly available in QML - it would be enough to have it as an internal function.
