I plan to start with references. I'm at the point where I can use them, but don't totally understand them. I figure the pressure of having to explain them to a (small) class might push me over the edge. (one way or the other)

I don't think I'll be able to teach anyone how to write objects, but I do want my students at least to be aware that they exist, know them when they see them, and be able to start to use pre-written modules like CGI
