Sorry, this part isn't correct (at least, I don't think it is): "(e.g. 
the `let' and the `add-hook' were in different functions)". So just 
ignore that bit. :)

Nevertheless, it could be that the bound variables in a closure aren't 
what you'd expect, so I still think it's useful to see them somehow.
