I had this issue with Lua 5.1.  It "works" for medium-ish 
integers, but as soon as you're encoding data in ints, such as 
unique IDs made up of multiple components that may have high bits 
set, it'll fall apart.  I am still using Lua 5.1, but now I 
just.. don't do that anymore.  Unfortunately if you want to pass 
along data that would otherwise be a 64-bit int, you either have 
to send along a raw pointer or else create a Lua-GC-allocated 
object to hold it instead (and at that point you may as well just 
use userdata for the D object itself).

While not recommending it as such, I believe Julia supports 
multiple int types, though my cursory examination suggested the 
performance and resource draw is far, far worse than Lua.
