[plt-scheme] Is sharing unit tests for problems in HtDP a good way to facilitate learning?

That's a generous offer, but students need to learn to write their own
tests.  It's an important skill, and for that reason it's also often a
graded part of the assignment.  On a mailing list, you never know
what's graded and what's not, so it's usually best to point the
student in the right direction, but not contribute any new material to
their work, no matter how innocuous it may seem.
