Most of the "tips" in this article seem to suggest choosing a bad naming scheme or intentionally misnaming variables / functions. I can't imagine it would be that hard to put the code into an AST and work with that. That would make it easy to see where variables are used (despite losing their names). I realize that would take extra time, but I don't suspect it would be quite as bad.

I'm more afraid of the "Use threads With Abandon" tip.
