Right, I've seen these to be helpful.

The global task would allow to code like this.
struct MyStruct
    int property1;
    QString property2;

class MyObject
public slots:
    void mySlot(const QList<MyStruct>& value);

QJsonDocument doc(...);

QMetaMethod mySlot(...);

JsonDeserializer deserializer;

QVariant parameter;
if(deserializer.deserialize(doc,  mySlot.paremeterType(0), parameter)

The only difference from examples, is that library user specifies, what
datatype should be produced. This would alllow to significantly reduce the
amount of boilerplate code.
