## all-external-formats

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.

### Examples:

    (let ((before (all-external-formats)))
       (def-external-format :test)
       (set-difference (all-external-formats) before))
          -> (#<external-format :test>)
