Might work for QList<QByteArray>, but for most types, no. Explicitly
instantiating QList also instantiates (parts of) QVector, QSet, and std::list,
by way of toSet/toVector/toStdList members (this is one of the reasons why you
shouldn't add as members what you can add as non-member) which adds having a
default ctor and a qHash() overload to the requirements on the type, on top of
what QList requires.
Not all types satisfy that, e.g. QPointF.
