If we broaden the discussion to the greater Lua ecosystem as opposed
to limiting our scope to PUC-Rio, this can be relevant even in a
scripting language. An implementation such as LuaJIT (which I wouldn't
be surprised to see pick up the new bitops even though it hasn't
picked up many 5.2-isms) that generates machine code would benefit
from these kinds of optimizations.
