about conditional relationships, needs to change. I only see one such case, the one we're talking about here.
My biggest complaint wasn't about the use of the word 'converse'. Instead, it
was the explanation of 'unless' as an 'if without a then'. I think it needs to
explain that it is an 'if without a then but with an else that is populated
with the expressions from the then block of the unless statement. An example
like the one in the Lisp Reference Manual would bring it home. I'll include
that change in my patch and you can decide whether it's appropriate..
