Hi I have installed GNU GCL and it works fine, except the case, for
example,
(defun length4 (list)
(loop for element in list count t))
When I try to use the function length, I get
Error: The variable FOR is unbound.
Fast links are on: do (si::use-fast-links nil) for debugging
Error signalled by LOOP.
Broken at LOOP. Type :H for Help.
The smae problem with loop-until, etc.
Any ideas?
Thanks,
-Jae

Try using CLISP (http://clisp.sourceforge.net/) instead. I tested your
example, and it worked fine. In addition, CLISP is still being actively
developed, while AFAIK GCL isn't.

In gcl 2.3 the sloop package provides the sloop macro which
doesn't conform to the loop of the standard. Look at sloop.lsp.
Anyway, you can say:
(require "SLOOP")
(use-package "SLOOP")
(sloop for i in '(Common Lisp is a rich Language) count t)

You can also get a real loop implementation from the CMU AI Archives.
I've done this and it works.

You can also dump GCL and get a better CL.
