Instead of export lists, we could have exports on individual items.

So, instead of:

fn foo() { ... }
export foo;

We would have:

pub fn foo() { ... }

And instead of:

import foo::bar;
export bar;

We would have:

pub import foo::bar;

(Here I changed export to pub to better match classes and to avoid exceeding the 5-character limit, but I'm ok either way.)

This change would help avoid the pain of managing export lists and should make libraries easier to write. Often people look at the definitions of items and want to know then and there whether the item is public or not.
