Subject: CL compatibility question
Date: Thu, 06 May 2004 14:36:09 -0500 [thread overview]
Message-ID: <E1BLofB-0007kA-00@linux183.ma.utexas.edu> (raw)
Frode Vatvedt Fjeld suggested (on comp.lang.lisp, 2004-05-06) the
following approach to building something like Bash's `$@' in LISP:
(defmacro defbashfun (name lambda &body body)
`(defun ,name (&rest $@)
(apply (lambda ,lambda ,@body) $@)))
In CLISP, this works great.
(defbashfun taco (beef beans)
(car $@))
(taco t nil)
;=> T
In ELISP, not so great.
(defbashfun taco (beef beans)
(car $@))
(taco t nil)
;=>
Debugger entered--Lisp error: (wrong-number-of-arguments (lambda (name lambda &body body) (\` (defun (\, name) (&rest $@) (apply (lambda (\, lambda) (\,@ body)) $@)))) 3)
(lambda (name lambda &body body) (\` (defun ... ... ...)))(taco (beef beans) (car $@))
(defbashfun taco (beef beans) (car $@))
eval((defbashfun taco (beef beans) (car $@)))
eval-last-sexp-1(nil)
eval-last-sexp(nil)
* call-interactively(eval-last-sexp)
Why is this? Are there plans that would change this behavior in the
future?
