Well I like this idea! But your concerns are valid.
So the section will be very clear as to what the real goals
are. The section will have an explanition just like Snippets
or Code; Being very clear that the answers are hints! If the student can't understand and wants to give up, let them do
pennence before getting the answer (submit the work they have done
work on the problem so far). My favorite post is a snippet for
a password generator. I learned so much just from other monks taking the code
and improving on it. That's what this site is. This node could be
a lot of fun!
