[Interest] QMetaType::registerComparators<T>()

[Jérôme Godbout]

Hi,

I would like to know if this is possible to do the following registration
and use the comparator operator into Qml javascript after:

// Toto.h
struct Toto
{
  bool operator< (const Self& other) const { ... }
  bool operator==(const Self& other) const { ... }
};

Q_DECLARE_METATYPE(Toto);

// During plugin registration
qRegisterMetaType<Toto>("Toto");
QMetaType::registerComparators<Toto>();

Should it be possible to use the operator< into Qml javascript with 2
object of this type? I currently (Qt 5.5.1) cannot seem to make this work
and I wonder if I understand properly the registerComparators
http://doc.qt.io/qt-5/qmetatype.html#registerComparators
like into the following exemple?
http://doc.qt.io/qt-5/positioning-cpp-qml.html

If anybody have a hints or information on this I would be grateful.
Thanks,
Jerome
