But moc could not produce code like this, so I would say it is not "just fine":

- header:

template<class T>
struct A : public QObject
{
signals:
     void aSignal(T);

public:
   void foo(){...}
};

- somewhere:
A<int> a;


- moc file/header:

template<>
struct A<int> : public QObject
{
     Q_QOBJECT

signals:
     void aSignal(int);

     // simple copy of code in base template
     void foo(){...}
};

  + the typical moc code



But for this all source code needs to be scanned,
not only the headers.
