Does this mean that if we don't pay attention to this new behaviour we
could get worse performance than Lua 5.2/5.1 or the only drawback is
simply that we wouldn't gain any performance boost from the new int
arithmetic? May existing scripts exhibit worse performance in 5.3?
In other words, I'm worried that people who don't need this "automatic
int management" could possibly suffer from a performance hit, _forcing_
them to be more careful when writing code.
BTW, besides the new operator/functions/features, could old scripts also
experience a change of semantics? And to which extent?
