I heartily agree that the bit32 functions in Lua 5.2 are kludgy,
and don't deserve the status of belonging to the standard library.
Prediction: bit32 will be deprecated in Lua 5.3, if not already
omitted from the beta release of Lua 5.2.
Everything about it screams against the Zen of Lua: it's
hardware-specific, not extendable, not surprisingly powerful,
not compelling at the abstract level, motivated purely by issues
of performance and implementation ...
This stuff belongs in C, not Lua.
