Yes, see earlier in this thread: if you #include your .moc in your .cpp,
your .h can get away with forward-declaring some classes whose headers
it doesn't #include; the .moc may need to see the actual definition,
rather than a forward declaration, and the .cpp shall do the needed
#include, hence make the definition visible, which the .moc then
benefits from by being #included in the .cpp.
