Update: there where missing string-quotes, error changed:

(defun foo1 ()
   "[Some docu]

(defun other-foo "
   (interactive)
   ;; defining another function inside
   (defun foo2 ()
     (interactive)
     (message "%s"   "Foo2")
;; another syntactically correct function just badly indented
(defun foo3 ()
   (interactive)
   (message "%s" "Foo3"))
       )
   (message "%s" "Foo1"))

;;;;
Results of evaluation:

(foo1) ==> "Foo1"
(foo2) ==> foo3 ?
(foo3) ==> "Foo3"
