[Interest] Caching of compiled/initialized qml code to disk possible?

[Juergen Bocklage-Ryannel]

Hi,

We are currently working on a project where we cache all screens on 
start-up, by using
Qt.createComponent(url). By this the major components are parsed and 
cached on start-up. It has also a second benefit, it verifies your 
components on syntax error on start-up.

For my knowledge the Loader element will try to load the component later 
and will hit the cache (as the URL is the same).

Actually we go even a step further to create a large registry of all 
application screens so we can call the screens by the registered name 
and not the component url.
