Hmm. On closer inspection, I'm going to have to amend my implictation
of Scheme: the example poster was cheating. Scheme and Python both do
closures the same way. However, the Scheme snippet in the original
example used a let-block. I.e., it introduced a new scope, whereas the
Python example did not (because it doesn't have anything like let).
