strict QML

Description

We need to figure out the exact specifics of what we can or cannot support in strict QML.

The high level descriptions sound nice, but are certainly incomplete and the devil will definitely be in the details.

In order to learn more about this, we need to write a prototype and try to port some example code from dynamic to strict QML.
