| It would be interesting to know what implementations return for the
| following:
|
| (defun nleft (n x &optional tail)
| (loop for v on (nthcdr n x)
| for w on x
| when (eq v tail) do (return w)
| finally (return w)))
|
| (nleft 1 '(0 1))
|
| SLOOP says '(1), while MIT LOOP says '(0 1). I had assumed MIT LOOP is
| correct but I haven't checked.
clisp-2.33.1 on cygwin and clisp-2.33.2 on irix6.5 give (0 1)
