Thanks, I value that feedback quite a lot because I was initially feeling quite unsure about it. As I've done a little more research I think it's pretty clear that...

Back to pointers as default. We use the `unsafe_getvalue`, `unsafe_isnull` and `unsafe_construct` methods. All `setindex!` and `setnull!` methods are still safe and will probably remain so, as there aren't really...
