The tradition for obfu in general is that you must understand before you run. Doing otherwise is at your own risk.

Here at pm, we've been moderate about that and generally frown on destructive code. That custom is not to be relied on, because it can be and has been broken at times.

We tend to cite the bigger tradition, laugh, and go on when it's broken. There are usually considerations and cries for Something To Be Done. Little comes of that since the thing called to be done is quite impossible (some flavor of halting problem).
