Are you sure that my patch will work properly?  I was looking at it, and
it seems like the use of org-let might cause the list (the code) to be
evaluated at run-time, and not at compile time, right?

Here's org-let:

(defun org-let (list &rest body)
  (eval (cons 'let (cons list body))))
(put 'org-let 'lisp-indent-function 1)

It occurs in org-agenda.  Question:  does this mean that the backquoted
expression will be evaluated at run-time, or is the compiler aggressive
enough to do it at compile-time?  This is something I /should/ know, but
