The compiler knows a lot more about syntax extensions than it ever should have. There's a danger that our syntax extensions could become hopelessly intertwined with rustc. We need to get a real plugin mechanism working before it is too late.

Depends on #458. See alse #38.

Examples of where the syntexts are (or might become) intertwined?

As far as I can see, the only ones are quasiquoting and macro_rules!. #[derive] could become intertwined (but it's not). Anything else?

I think this issue is moot so I'm closing it.
