> The code bloat argument against FixedSizeList does not apply to List / LargeList: the GroupColumn implementation is able to dispatch dynamically on the child array, the only monomorphizations are for the two offset types. I am not sure how this would work -- you will need to find some way to nest the group storage otherwise you'll have to instantiate (and make code copies) for each combination you want to handle (List<Int8>, List<Int16> ...) . You need something more like List<dyn Storage> ANd somehow reuse the dynamic storage for each nested type without having to instantiate all the possible combinations -- This is an automated message from the Apache Git Service.
