Thanks Mattais, I certainly appreciate this list being so responsive
and helpful.  And I definitely wouldn't post guesses asking for the
answer, since I'm spending my own time to really learn the material,
not just pass a course.

It's just a less efficient workflow to post my solutions to the list
asking for feedback, vs being able to quickly click, compare mine to
the correct one, and move on.  Instant feedback speeds up the
Read->Code->Understand loop.

Having already worked through The Little Schemer, I'm getting most of
HTDP's exercises right so far, at least in terms of them working in
DrRacket and returning correct answers.  But there are usually
variations on how the program can be correctly written, and that's
what I was hoping to be able to check against the authors' solutions.
