(LAST '(A B . C)) --> C

which is essentially useless.  I think it should return the last cons in the
structure.

(LAST 'A) --> A
(LAST 3) --> ***MISSING-ARG***   (meaningless error message)
(LAST 3.3) --> breaks lisp
(LAST <bignum>) --> <list of fixnums>

I think the right thing to do is to have the last four cases be errors and
to print the fact that LAST was called with a ridiculous argument and print
the argument.
