A direct use case of this is to support having Q_OBJECT classes defined 
in a .cpp file. That requires moc to parse foo.cpp file and produce foo.moc.

The question is, does this happen unconditionally when a #include 
"foo.moc" appears a .cpp, even if that .cpp is not using Q_OBJECT & 
friends? Why would it be necessary in this case?
