I'd use the higher-level MAP-CLASS instead:

(defun first-ten (classname) ; untested
  (let ((i 1) result)
    (map-class
      (lambda (o)
        (when (> i 10)
          (return-from first-ten result))
        (push o result))
      classname)
    result))

That doesn't work if you want to start somewhere in the middle,
though.
