Why not directly use vclass.cast ?
I think there may be a subtle change in behaviour with the updates to A*FU,
where previously a CCE would be thrown and now a IAE is thrown e.g. consider an
erased A*FU to a public field of some class and and a receiver of the incorrect
type is passed to an access method. Does not really matter in practice,
although the error message will be confusing.
