Should it delete the variables, or should it be a new scope? They're
subtly different.
If the former, how do you differentiate a variable initialized in the
block from a variable assigned in the block? What if you really *do*
want to keep one of them? (The answer in both cases if it's a new scope
would be to use "nonlocal")
