Now I see -- that's great, thanks. (It was the missing UNIQ that got me, I can add parens :))

I think that if we kept going down this direction we would eventually come up with a macro system that was "hygienic in practice". Building a good and simple hygienic macro system is a very achievable goal.

All I really want to say is that there isn't a trivial silver bullet solution: A simple module system doesn't fix name collision. A simple code walker doesn't fix it (it needs integration with the environment.)

I eagerly await the version of Arc that has a macro system where name collision can be avoided.
