Dear Emacs maintainers,

I'm trying to setup a clean set of skeletons, but it turns up that I
can't call a skeleton from another. The method I tried raises the error
message:

"skeleton-internal-1: Variable binding depth exceeds max-specpdl-size"

I tried to write a basic test to demonstrate the problem.
Here it is (nested-skeletons.el) :
**********************************************************************
;; Each skeleton is followed by a sample output

(define-skeleton tst:plain
  "No prompt skeleton."
  nil
  "; I'm static text inserted by skeleton tst:plain"
)
; I'm static text inserted by skeleton tst:plain

(define-skeleton tst:use-str
  "Interactive skeleton."
  "Message: "
  "; I'm generated text (" str ") inserted by skeleton tst:use-str" \n
)
; I'm generated text (yes) inserted by skeleton tst:use-str

(define-skeleton tst:skeleton-caller
  "Calls another skeleton"
  nil
  "; I'm lazy. I want to reuse some ready-made skeleton" \n
  (tst:plain) \n
  "; Happy to see you again." \n
)
; I'm lazy. I want to reuse some ready-made skeleton
; I'm static text inserted by skeleton tst:plain

;; The cursor stops just after "plain", and I get the error message:
;; "skeleton-internal-1: Variable binding depth exceeds
max-specpdl-size"
;; or "skeleton-internal-1: Lisp nesting exceeds `max-lisp-eval-depth'"
;; in some previous sessions

(define-skeleton tst:skeleton-caller2
  "Calls another skeleton"
  nil
  "; I'm lazy. I want to reuse some ready-made skeleton" \n
  (tst:use-str "toy") \n
  "; Happy to see you again." \n
)
; I'm lazy. I want to reuse some ready-made skeleton
; I'm generated text (toy) inserted by skeleton tst:use-str

;; same result
;; ============================================================

**********************************************************************
Please tell me if
- I did something wrong
- you need more information
- nested skeletons are not supported
- you can't reproduce the problem

I'm working on Ubuntu with emacs-snapshot package, and I still have
emacs22.

Thanks a lot.
