That's not a first-class function call. All first-class functions need to be callable, but not all things at the head of a list need to be functions. To use Lisp terminology, Java methods are special forms. They can't be treated as first-class functions. Common Lisp example: cl-user(2): (mapcar 'progn (list 1 2 3)) Error: Attempt to apply or funcall progn which is a special form.
