[Gllug] XOR

[Ashley Evans]

Afternoon,

Having spent the day working on various bits and bobs I came across some 
info on wikipedia about XOR.

The two notable things I've discovered today are:

One can swap the contents two vars without using a tmp var.
One can implement a doubely linked-list using .

Then we have the good old xor "encryption". Which is fun to play with.

As a newbie programmer I think xor is about a great as functions come.

So, what else can this bit of binary operator magic be used for?
