Aaaha:) I must say, one reason, why I'd like to have it wrapped is
that VarHandle.get/set do not have fixed typed signature.

Helper.longAt(arr, index) looks much better than
SOME_STRANGE_CONSTANT.get(i can write here what I want and compiler says
nothing:);

I should have started to write here earlier;). So, what will we do with it?
