I have almost no clue what you're doing, but I hope it works out. Treating core variables differently than others sounds nothing like what I would do, so we're separate people. :-p
Yes, it's ludicrous, crazy, and probably insane, but I'm trying it anyways. I suspect it'll break later, though, so I'll have to go back to lexical-scope-for-everything.
By the way, I called it dynamic scope, but I'm not actually sure what it is. It's this weird short-circuiting thing that causes the global_env to jump back one environment level, which then causes it to loop back onto itself if the variable isn't shadowed, but it works (for now).
Edit: nevermind, I had to revert it. Darn. It was such a silly hack too.
