1. values returned from the assignment are not the effective ones
2. .href value after setting an empty hash is browser-specific
3. It seems as though HTMLAnchorElement and Location might share the same implementation in all browsers except IE

Also, location = location.href triggers a reload, but location = location.href + "#" doesn't
