Correct :) Though incidentally not IRC this time, but an e-mail conversation. Anyway, this issue popped up relatively often during the last years. My impression was that some people naturally expect syntax highlighting, or even demand it, and I felt I should also make my position clear. > > As I understand it, syntax highlighting marks symbols which are > > "keywords" in the language.

Yes, as I said, comments. There isn't much more syntax to Lisp, except for the parentheses.
