Backtick & comma introduced w/o explanation

[lojic]

In section 3.4, you introduce ` and , in the our-if-v2 macro. I know about the interplay of ` and , from fooling around with Common Lisp a bit, but that was the first I've seen them used in Racket (still very new), and some people may not understand their use at that point in your tutorial.

Thanks for the feedback! Writing stuff like this is hard, because you have to decide how much your readers already know. Assume they know too little, and it gets tedious and boring. Assume they know too much, and they won't understand.

Your comment gets to the fact that I assume readers know roughly as much about Racket as I did, when I was recording my struggles to learn about macros.

Although that's probably true for many readers, it wasn't for you. I'm not sure I can solve that in general (see the "tedious" point, above). But I could try to address this specific thing. :)

I'll take a stab at that. If explaining quasiquoting becomes too long a digression, however, I might have to just link to someone else's explanation. Hopefully that would still help.

Thanks again for your comment!
