This one is unlikely to happen because I need to be able to translate the query into SQL and there is no way to do this in SQL. It may be possible for a pure Java database, but I don't know of any that support that. It would also be very slow, because you would have to deserialize every object in every row and then execute a method call.
It was a good idea anyway. I would like to be able to support arrays this way because a lot of databases do support SQL arrays.
