Using `backtrace-frame', this almost worked:
(defun function-stack ()
(cadr (backtrace-frame 3)) ) ;;; 3 = function-stack-caller (look below)
;;; 2 = function-stack
;;; 1 = cadr
;;; 0 = backtrace-frame
(defun function-stack-caller ()
(function-stack) )
(function-stack-caller) ; function-stack-caller! <success music here>
;; however...
(defun function-stack-embedded-caller ()
(if 'some-error-check (function-stack) ))
(function-stack-embedded-caller) ; if! so doesn't help...
