This is an unbirthday present for @screwlisp,
who posted earlier about quines.

To give it as a puzzle at first:

find a Python quine as a string Q such that eval(Q) == Q.

A spoiler to follow.

_________
The term "fixed point" comes to mind. And the Y combinator comes into
this picture as well; wie another day.

(Estimating Python's degree of homoiconicity is left as an exercise.)

It's very simple to make a readable function to generate an increasing numerical sequence that wraps using the modulo operator.

num = 1;
1
num = (num % 3) + 1;
2
num = (num % 3) + 1;
3
num = (num % 3) + 1;
1

The reverse function I came up with seems unreasonable and unreadable!

num = 3
3
num = (((num + 2) % 3) + 2) % 3 + 1;
2
num = (((num + 2) % 3) + 2) % 3 + 1;
1
num = (((num + 2) % 3) + 2) % 3 + 1;
3

Am feeling tired ;-)
