most ambiguous line of code ever written?

[Mark Lawrence]

I wanted a piece of code to write alternatively to the left and right 
sides of a deque.  I remembered a stackoverflow question about toggling 
with an excellent answer from Raymond Hettinger.  So I now have this.

right = not right

Isn't that just beautiful?
