After stripping those annoying `local`s in order to run your code
from the standalone interpreter, it works just fine on Lua 5.2.2
under Ubuntu 12.04. The last expression returns 4, as it should.

You _are_ running latest versions, yes?

BTW you missed "\195\183" as a divide synonym.

Probably system-dependent.
