While I agree with this overall, there's still one caveat which I
haven't seen discussed yet:
Imagine I have the following code:
property color prettyColor: "#f0f"
Right now "foo" refers to the Item. What if in a future update,
Rectangle gains a new property "foo". Unless you want to force everyone
to be explicit by using "this" (e.g. width: this.height) everywhere,
which would be annoying, I don't see how this can be made future-proof
without some form of versioning or some other magic solution?
