The way the Eval PMC worked was that it returned a list of Subs, and I think the one at index zero was the sub marked :main. The PackfileView PMC has a method .main_sub(), which does the same thing more explicitly. At least, that's how I remember it. so it's the same Sub being executed, we just get access to it in a different way.
