keywords

["Scott E. Fahlman" <Fahlman@C.CS.CMU.EDU>]

It is certainly terrible style to use a keyword as the name of a
function or to give it any properties.  The book doesn't seem to say
whether "it is an error" to do either of these things.  I think it
should be an error.  On the other hand, I don't know of any Common Lisp
that goes to the trouble of signaling such an error or that special
cases keyword symbols in such a way as to eliminate the function and
property-list cells.
