Subject: elisp functions that take unevalled args

Is there a way for an elisp function to take unevalled arguments?
I haven't found one.
It would be nice to be able to say:
(defun frobq (vars &unevalled args) "Frobnicate and setq"
(let ((frobnication-value val))
(setq args)))
The actual use I would like is to have a conditionalized progn:
(defun if-loadable (package &unevalled body) "\
Execute the BODY forms if PACKAGE is, or can be, loaded."
(and (or (featurep package)
(load package t))
body))
