Functions are wrapped now.  There's a tiny tiny bit of slowdown, but not too bad.
Getting a weird error with Cookie Clicker, the current test app.  I think they're attaching something to their functions which isn't getting carried over.  I'll try to fix it, but it isn't a huge emergency - I think it's them doing something weird, and most programs we won't run into it with.
