Bel is a spec for a new dialect of Lisp, written in itself. This should sound familiar to people who know about Lisp's origins, because it's the way Lisp began.
It consists of two text files meant to be read in parallel: a guide to the Bel language, and the Bel source.
For those who just want to see some code examples, there's a file of those. But of course the Bel source is also a code example, since it's written in itself.
Considering the rate at which I was discovering bugs before publishing Bel, there are bound to be more remaining. So this first version is version C, after Cunningham's Law.
