I'm asking because something went across p.r.c today asking about the

differences between CL and Scheme's macro systems and syntax-case came

up a lot in the comments/discussion.

You might try out _The Scheme Programming Language_ chapter freely

available here http://scheme.com/tspl3/syntax.html#./syntax:h3

It's from R. Kent Dyvbig, who I *think* is the original author (or one of) of syntax-case.

It's not as enlightening as JRM's primer on syntax-rules, but if you now are

comfortable with syntax-rules, syntax-case does nothing more than allow you to

break hygiene. The pattern language is still the same. The only thing to really

learn are the techniques used to create the unhygienic portions of your macro. I

admittedly haven't done much with syntax-case, so I may be off a bit.

Good Luck
