Very interesting. Both this and creating a "function creator 
function" work, and it seems clear that functions create their 
own scopes. However, it seems that loops do not, is that correct? 
  Maybe I was thrown off by the surrounding `{ }`, but I had 
assumed that loops created their own scopes.
