Understand clearly that NetWallah is suggesting something that can break things very easily and subtly.

Please review that post, where it was said "not a good idea".

Do not break things like this. Do not work this way. It was a concept piece of code that shows 'how' you could do something, not how you *should* do something.

If you continue on this path now, you'll do so going forward. Don't.

Proof of Concept chunks of code are just that... tests.
