Core code recopied into a pastebin instead, if that's your only
problem.

I hardly call 87 lines of code "miles of code" though myself.  I call
it a relatively trivial example aimed at showing the benefit of using
super() in your code rather than hard coding brittle fragility into
your code.

No, it was a thought out example of how writing code slightly
differently from how you do now can result in something more
practical, reusable, extendable, and maintainable. I was hoping to
educate you as to why one approach *might* be considered better than
another.

Deriding is as you do completely misses the point, sadly.
