xor and class?
 

I've been wondering what these do. When you type them into the compiler, they turn red like "if" and "function" do. How are they used on graal? And is there really any situation in which you would use these over alternative code?

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.

Doesn't Graal have other logic gates? (NOT, AND, OR, NOR, XOR, XNOR, ...).

I think I recall trying other logic gates, but they didn't come up with red letters. So I'm guessing not. :p

& is bitwise and, | is bitwise or. GS2 also offers >> and << for right/left shift (respectively, duh). Not sure about others. It's possible that ! also works as bitwise negation, give it a try.

Could have sworn I tried a %= b; one upon a time. Don't remember if it ever worked. I thought I was told it wouldn't :(
