That's exactly how I feel towards this whole S-expression deal.

I didn't know anything about lisp or cons pairs (except that lisp
involves lots of nested parentheses), I just stumbled on Rivest's de
facto standard when I was looking for a simple and easy-to-use
external data format.

And since then I've always been alone with that format. Usually it was
because people freaked out because of parentheses, now it's because
I'm doing everything wrong (i.e. not according to the one true cons
pair idea), but the end result is the same.

Anyway, I knew from the beginning switching from C to Ada won't
increase the number of people using, or even only reading, my code.
Starting from 1 (me), the result was very predictable.
