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...
