Hi,
Apparently and is not a normal function like +, -, ...
AND is a macro (because it may decide not to evaluate some of its arguments).
See http://www.lispworks.com/documentation/HyperSpec/Body/m_and.htm
I can write (and t t nil), but if the parameters are packaged into a list,
how can I do?
One thing to do is to (let your Lisp) write exactly that (using a macro your
self).
