from reading the elisp manual, it seems that one could define those
variables to be "special variables", and, iiuc, one can achieve this by
using a =defvar= without a value, previous to the =let= where values are
assigned.  something like (for just full-block):

diff --git a/lisp/ob-core.el b/lisp/ob-core.el
index af2c9912e..a0528bb06 100644
--- a/lisp/ob-core.el

         (while (re-search-forward org-babel-src-block-regexp nil t)
           (when (org-babel-active-location-p)
             (goto-char (match-beginning 0))
+            (defvar full-block)
             (let ((full-block (match-string 0))
                   (beg-block (match-beginning 0))
                   (end-block (match-end 0))

i could do a patch in this style, for all these variables.

cheers, Greg
