Build a symbol in the C package from a list of atoms.
This is a concise wrapper of the built-in packn-pos, specialized for the C package. This macro takes any number of arguments, which are evaluated and put into a list passed to packn-pos; thus, the arguments must all evaluate to atoms.
Macro:
(defmacro pack (&rest args) (cons 'packn-pos (cons (cons 'list args) '((pkg-witness "C")))))
