So swap(a, b) swaps the contents of a and b. This could be easily

know applications for three arguments. Thoughts? -- Andrei
One thing that screams out to me: this should be called rotate, not swap.
Yes, rotate(), but then I would never remember what direction it rotates.
Use the law of UFCS:
x.rotate(y, z); // x-> y, y -> z, z -> x
