[plt-scheme] HtDP in Python!

1. The whole point of the HtDP methodology is that it has nothing to
do with Scheme.  It's a universal recipe across programming languages,
which is why we refrain from syntactic tricks (which are numerous and
easy to build in Scheme).  HtDC makes this point explicit in Java; a
whole family of HtD* can make this point explicit for other languages.

2. Try the same with a tail-recursive program and see how far it goes.

3. You still have about 679 pages to go to meet the challenge of your
subject line. (-:

4. Then you can port DrScheme, too. <-;
