xor and class?

[Crow]

xor, usually the ^ operator in other languages, is bitwise exclusive or. Compares the two inputs bit by bit, bit output is 1 if one bit is 1 and the other is 0, otherwise 0.

For example: 3 xor 5 == 6
Because:
3 == 011
5 == 101
6 == 110


Not sure if the class keyword is actually being used.
