Greetings! It is well known that TeX’s count registers, \count0 thru \count255, have a range of 2^32 integers (from -2^31 thru 2^31-1).
Lua 5.3, released in January 2015, introduced an explicit integer numeric type. Integers are now stored and processed as 64-bit items. If and when LuaTeX switches from Lua 5.2 to 5.3, will the range of permissible integers in TeX counters be expanded from 2^32 to 2^64, so that they can range from 2^(-63) to 2^63-1? Just curious. Best, Mico
