There should be a way to figure out if Item's anchors are "connected", so that it would be possible to avoid trying to set the size explicitly when anchors are handling the width. This way it would be possible to avoid binding loops. There is "Anchors usedAnchors()" method in QDeclarativeAnchors, but is is not possible to call it from QML. That, or any other way to do this would be great. Also enum Anchor should probably be exposed to QML.
