Speaking as someone who has almost no clue about QtRO, from an engineering 
pov, it feels weird to have an easily-parsable representation of a 
QMetaObject, then generate C++ code from it, and then use moc to parse the C++ 
code to generate a QMetaObject. Wouldn't it be much simpler to generate the 
moc files directly from the rep files (maybe even at runtime, with 
QMetaObjectBuilder)?

Thanks,
Marc
