HBox and VBox and horizontal and vertical layouts probably wouldn't work as expected if this

I can see that could complicate things. May be possible for the bindings to execute once before
needed components have been created if you are using states.

For the most common use case ie const + "const" expressions there's no issue. Most users (unless
they wanted to optimise performance) are likely to continue to use existing normal binding.

There is also a very simple fix if something doesn't work the way you expected - just go back
to using normal binding.

You have anything you can submit or code we can look at? It certainly sounds like a sound
approach but I no idea how much work it would take.
