For the first time in 20 years I used and xor operator.
I wrote in line of code instead of two.

How uses the xor operator?

When you want to output to be false when same and true when different. What do you mean how does one use XOR?

I'm confused. Can you be more specific?

Are you into men xor women

Only when I want to confuse the fuck out the next dev.
I output errors messges using a random key xor'ed string. unique per error msg. Let them have fun searching trough the code...

You can use it to toggle specific bits:
x ^= 0x01;
This will leave all bits of x as they are, except the least significant one, which will change its state.

I use the XAND operator instead.

I would stay away from bitwise operators unless your doing operations on bitfields.

You can do clever things, but they aren't very clear for maintenance. Maybe if you put it into a well named function call or macro and it's there for speed purposes only.
