Don't worry, Bryan, I'm probably more to blame, since I have this tendency to
interject parenthesized sub-sentences all over my paragraphs, that probably
confuse more than clarify things ( self.remind(prose is not code) :).

Perhaps I should crosspost my replies (esp. the ones with nested parentheses) to
comp.lang.lisp ...
