Exercise 1: Detecting a Long Parameter List — Possible Solution
====================================================================

THE EXTENDED CHECKLIST
------------------------------
    def smell_aware_checklist_v2(code):
        ...
        if len(params) > 6:
            issues.append(f"function has {len(params)} positional parameters "
                           f"(Clean Code Ch.4: long parameter list)")
        ...

RESULTS
------------------------------
    BAD code (create_order with 8 params):
      ['function has 8 positional parameters (Clean Code Ch.4: long
       parameter list) - line: def create_order(order_id, customer_id,
       items, shipping, discount, priority, express, address):']

    GOOD code (create_order with 4 params):
      []  (no issues found)

The checklist correctly flags the 8-parameter version and leaves the
4-parameter version untouched.

WHY THIS WORKS AS AN ANSWER
------------------------------
This confirms the chapter's own "smell-aware checklist" concept
generalizes to a second, genuinely different category of smell -
Clean Code Chapter 4's own long-parameter-list finding, not just
Chapter 8's own duplication finding. Both smells share the same
underlying property that made the chapter's own duplication check
possible: they're detectable directly from the code's own structure
(parameter count, repeated logic) without needing to run the code or
understand its business intent - exactly the category of check a
smell-aware review process can catch mechanically, distinct from
design judgment calls that still genuinely require a human reviewer.
