Q followed by lowercase letters used to be reserved for third-party 
implementations. The Q in Qt classes means Qt itself, it's not the first letter 
in another acronym. So these classes should actually be called "QQml".

I'm more worried that we're now duplicating the entire set of QML language-
support classes in the Qt Quick 1 and 2 modules. That means there's absolutely 
no chance of compatibility in C++ between 1 and 2...

But was there any? I mean, if the use of the scene graph already made every 
single C++ usage of QML have to be modified, there's no further harm by 
renaming some classes.

One final question: is it possible for the Qt Quick 1 module to use the Quick 2 
language module (QT += qml) and simply wrap it with its QDeclarative classes, 
retaining compatibility?
