Re: quotation question + good lisp doc

Chris, are you going to replace the current jump-or-exec
with cycle-or-exec? If so, I won't touch jump-or-exec.jl for a while.
It seems good.

But the *filename* jump-or-exec.jl is really good, so we should't 
throw it away.

I'll work on it later, waiting my class enhancements, but what you
want must look like this:
(define (cycle-or-exec re prog #!key name match-class)
  (let (forward-name backward-name)
    (when (stringp prog)
      (setq name prog))
    (if name
	 (setq forward-name (concat "cycle-" name))
	 (setq backward-name (concat forward-name "-backwards")))
      (setq forward-name
	    (concat "cycle-" (closure-name prog)))
      (setq backward-name
	    (concat forward-name "-backwards")))
    (if match-class
          forward-name backward-name
          (cycle-or-exec-backend (filter-windows-by-class re) prog))
        forward-name backward-name
        (cycle-or-exec-backend (filter-windows-by-name re) prog)))))
This is closer to the original one. Here, 'intern' is not necessary.
(I learned what's 'intern'. :)

1. 'prog' can be string or function, as original.
2. If 'name' is non-nil, it's used as the name for command.
3. Else, the function name is used for command.

It may be trivial, but it's good to ask at ML, too, if you come across
a lisp riddle. If you don't know something, many don't, so asking here
helps to share knowledge. :)
