Tony, Dirk sent a good response. I would like to add to that that it goes beyond just bits in SEXP: adding a new type involved in arithmetics is not only a lot of work but has performance implications. Also it is unclear how it should behave in the int32_t, double, int64_t triangle of vector classes in that respect (they don't nest) while retaining compatibility (doubles promote because they are a superset, but int64_t cannot do that). I am yet to see a real use-case where 53-bits are not sufficient in integer arithmetics so it is unclear that opening that big can of worms (and breaking things) would have any benefit. Typically, the only use-case for full 64-bit integers is as opaque 64-bit storage (e.g., randomly generated IDs) but there arithmetics make no sense there and packages are already covering that need.
