I was hoping ruby2ruby would help, but I can't get it to run on my Windows
box at present -- will try again on Ubuntu later. If anyone figures out how
to do this I would be thrilled, as I'm trying to do a similar thing in
JavaScript. Said language at least gives you a Function#toString method that
gets you part-way there, but getting the values of variables if the function
was created inside a closure is something I've not cracked yet.
