I had this exact sample problem with my BASIC compiler. AND and OR
were both logical, and coming up with solutions for bitwise operations
was a little hairy.

The best solution was to use NAND NOR XOR SL and SR for those simple
operations. For one's compliment I was able to use ~, but I agree,
that shouldn't be used here. Likewise, I don't think C operators
should be used either, as Lua seems to lean more towards BASIC in this
area than C (and IMHO, the language should stay true to itself).
