Parse QML to QVariant?

[wooyay]

Hi all,
I have a number of quite complicated QVariant structures. Like this:

QVariantMap booster1;
booster1["power"] = 10;
booster1["dir"] = 45;
QVariantMap booster2;
booster2["power"] = 10;
booster2["dir"] = -45;

QVariantList boosters;
boosters.push_back(booster1);
boosters.push_back(booster2);
QVariantMap spaceship;
spaceship["boosters"] = boosters;

(This is just an example).

I am getting really confused because I have to define everything backwards.

Instead I would like to write it in QML syntax:

spaceship : {
boosters : [
{ power : 10,
dir : 45
},
{ power : 10,
dir : -45
}
]
}

Is there a parser or something that takes QML as input and returns me a QVariant?
Any tips on writing one?
I think this is a quite useful feature
