    @Xpray yes that might be necessary as well. I think this code does not solve all problems
but the most urgent ones. It still fails if expressions in a field become too large or the
unboxing. Or even the class itself. There are many limitation that could be reached:

    Do you have use cases where you reach the limits with my current implementation?
