pySCG, better code examples for CWE-783: Operator Precedence Logic Error

[myteron]

Need to come with better code examples as per comments below:

The “Non-Compliant” snippet uses pure expressions (bit ops, tuple permutation) with no side effects. The introduction claims risk from “expressions that read & write to the same object”.

The compliant solution has identical output. While it's certainly much easier to understand and maintain,
given the introduction I would expect examples that demonstrate "unintended side effects" or a result that is "surprising and incorrect"
