Arguments:
This function returns the list of all active external-format objects. This function is setf-able. Thus, one can effectively remove an external-format from the Lisp system by using (setf all-external-formats) specifying a list that does not include that external-format.
(let ((before (all-external-formats))) (def-external-format :test) (set-difference (all-external-formats) before)) -> (#<external-format :test>)
