All feedback welcome. Thanks. > --lhf Just curious, how does lua deal with the undefined bitwise (shift) operations on signed integers, like shifting a 1 bit into the most significant (sign) bit of a signed int. Also, note: http://www.lua.org/work/doc/manual.html#3.4.2 The sentence, "Both right and left shifts fill with zeros the vacant bits." is slightly awkward, "Both right and left shifts fill the vacant bits with zeros."
