I too am very happy to see what 5.3 is doing with ints. When I do data
encoding/decoding protocol work (e.g. Google Protocol Buffers, BSON,
etc), it would be very nice  to properly handle 64 bit integers in pure
Lua. This will go a long way to making Lua a first class player in data
protocol manipulation!
