Well, I was talking about moc above.

Good point.  But some of the work can be cached, e.g. the anchor can lazily get and keep the QMetaMethods for the setX and setY of the thing that it's going to move and the getters from the reference object, and just invoke() them repeatedly.  If they could be somehow converted to plain function pointers, I suppose it would be faster than calling invoke()? 

Or maybe we should make QQuickAnchorLine and QQuickAnchorsPrivate into templates so they can access other types of objects that have the same accessors.  QQuickAnchors itself could start with QObjects and choose the right template at runtime.
